A uniform solid sphere of mass M and radius R is rolling without sliding along a level plane with a speed v = 2.30 m/s when it encounters a ramp that is at an angle è = 27.6° above the horizontal. Find the maximum distance that the sphere travels up the ramp if the ramp is frictionless, so the sphere continues to rotate with its initial angular speed until it reaches its maximum height.

Oh, we've got a rolling sphere on a ramp! Don't worry, I won't roll away from this question. Let me calculate the maximum distance for you.

First, we need to consider the conservation of energy. The initial kinetic energy of the sphere is transformed into both translational and rotational kinetic energy as it rolls up the ramp. At the maximum height, all energy is converted to potential energy.

To start with, let's find the initial translational kinetic energy (KET) and rotational kinetic energy (KER) of the sphere.
KET = 1/2 * M * v^2
KER = 1/2 * I * (v/R)^2

For a solid sphere, the moment of inertia (I) is given by I = 2/5 * M * R^2.

Next, let's find the maximum height (h) traveled by the sphere. It is equal to the potential energy (PE) gained.
PE = M * g * h

Since energy is conserved, the initial kinetic energy (KET + KER) is equal to the potential energy gained (PE).
M * g * h = KET + KER

Now, let's put all the pieces together and solve for h:
M * g * h = 1/2 * M * v^2 + 1/2 * 2/5 * M * R^2 * (v/R)^2

Canceling out common factors and simplifying:
g * h = v^2 + 2/5 * v^2
g * h = 7/5 * v^2

Finally, solving for h gives us:
h = (7/5 * v^2) / g

Plugging in the given values: v = 2.30 m/s and g = 9.8 m/s^2, we can calculate the maximum height (h) traveled by the sphere.

Hmmm, it seems like this question is rather serious and not very suitable for clowning around. I apologize if my answer isn't as humorous as you may have expected. But I hope I've been able to assist you nonetheless!

To find the maximum distance that the sphere travels up the ramp, we need to consider the conservation of mechanical energy.

The mechanical energy of the system is the sum of the kinetic energy (KE) and the gravitational potential energy (PE) of the sphere.

At the initial point, the sphere has both translational and rotational kinetic energy.

1. Translational kinetic energy (KE_trans) = (1/2)mv^2, where m is the mass of the sphere and v is its linear velocity.

2. Rotational kinetic energy (KE_rot) = (1/2)Iω^2, where I is the moment of inertia of the sphere and ω is its angular velocity.

The total initial kinetic energy is the sum of translational and rotational kinetic energy.

KE_initial = KE_trans + KE_rot = (1/2)mv^2 + (1/2)Iω^2

Next, we can calculate the gravitational potential energy (PE) of the sphere when it reaches its maximum height.

PE = mgh, where m is the mass of the sphere, g is the acceleration due to gravity, and h is the maximum height.

Since the sphere is rolling without sliding, we know that the linear velocity (v) is related to the angular velocity (ω) by the equation v = ωR, where R is the radius of the sphere.

We can substitute ω = v/R into the equation for rotational kinetic energy:

KE_rot = (1/2)I(ω^2) = (1/2)I((v/R)^2) = (1/2)I(v^2/R^2)

Now, let's find the moment of inertia (I) of the solid sphere. The moment of inertia of a solid sphere is given by I = (2/5)MR^2, where M is the mass of the sphere and R is its radius.

I = (2/5)MR^2

Substituting this into the equation for rotational kinetic energy:

KE_rot = (1/2)I(v^2/R^2) = (1/2)((2/5)MR^2)((v^2)/R^2) = (1/5)Mv^2

Now, the total initial kinetic energy can be expressed as:

KE_initial = (1/2)mv^2 + (1/5)Mv^2 = (7/10)Mv^2

Since there is no external force acting on the sphere and no work done by a non-conservative force, the total mechanical energy, which is the sum of initial kinetic energy and potential energy, is conserved.

Therefore, at the maximum height, the total mechanical energy is equal to the potential energy:

KE_initial + PE = (7/10)Mv^2 + mgh = mgh_max

Now, let's solve for h_max (the maximum height):

(7/10)Mv^2 + mgh_max = mgh_max

Simplifying and solving for h_max:

(7/10)Mv^2 = mgh_max

h_max = (7/10)v^2/g

Substituting the given values into the equation:

h_max = (7/10)(2.3 m/s)^2 / 9.8 m/s^2

h_max ≈ 0.392 m

Therefore, the maximum distance that the sphere travels up the ramp is approximately 0.392 meters.

To find the maximum distance that the sphere travels up the ramp, we need to consider both the linear and rotational motion of the sphere.

1. Linear motion:
The work done by the net force on the sphere (W_net) will be equal to the change in its kinetic energy (ΔKE).

W_net = ΔKE

The initial kinetic energy (KE_initial) of the sphere is given by:

KE_initial = 1/2 * M * v^2

where M is the mass of the sphere and v is the linear speed.

The final kinetic energy (KE_final) of the sphere at its maximum height will be zero since it comes to a stop. Therefore, the change in kinetic energy is:

ΔKE = KE_final - KE_initial = -1/2 * M * v^2

2. Rotational motion:
The rotational kinetic energy (KE_rotational) of a sphere is given by:

KE_rotational = 1/2 * I * ω^2

where I is the moment of inertia and ω is the angular velocity.

For a solid sphere rolling without slipping, the moment of inertia is given by:

I = 2/5 * M * R^2

where R is the radius of the sphere.

At its maximum height, the angular velocity (ω) of the sphere is related to its linear velocity (v) by:

v = ω * R

Rearranging, we can express ω in terms of v:

ω = v / R

Substituting the moment of inertia (I) and ω into the equation for rotational kinetic energy, we get:

KE_rotational = 1/2 * (2/5 * M * R^2) * (v / R)^2
= 1/5 * M * v^2

The total kinetic energy (KE_total) of the rolling sphere is the sum of the linear and rotational kinetic energies:

KE_total = KE_initial + KE_rotational
= (1/2 * M * v^2) + (1/5 * M * v^2)
= 7/10 * M * v^2

Now, the work done by the net force can also be expressed as the product of the net force (F_net) and the distance (d) over which it acts:

W_net = F_net * d

Since the ramp is frictionless, the only force acting on the sphere is its weight (mg), which can be resolved into two components: mg*sin(è) perpendicular to the ramp and mg*cos(è) parallel to the ramp.

The net force acting along the ramp is mg*sin(è). Therefore:

W_net = mg*sin(è) * d

Equating the expressions for work done and change in kinetic energy:

mg*sin(è) * d = -1/2 * M * v^2

Simplifying and solving for d, the maximum distance traveled up the ramp:

d = -1/2 * (M * v^2) / (mg*sin(è))
= -1/2 * v^2 / (g*sin(è))

Note: The negative sign in the formula is because the distance traveled up the ramp is in the opposite direction to the displacement.

Now, substituting the given values (v = 2.30 m/s, è = 27.6°, and g ≈ 9.8 m/s^2) into the equation, we can calculate:

d = -1/2 * (2.30 m/s)^2 / (9.8 m/s^2 * sin(27.6°))
