The acceleration due to gravity on the moon is about one-sixth its value on earth. If a baseball reaches a height of 51 m when thrown upward by someone on the earth, what height would it reach when thrown in the same way on the surface of the moon? Answer in units of m

would the answer be 51m * 6 = 306m

since the height on earth is 51 meters and the gravity on the moon is 1/6 the amount of the earth

yes, correct.

yea, 306 is correct!

No, the correct calculation should be as follows:

The acceleration due to gravity on the moon is one-sixth the value on Earth. Therefore, we can say that the acceleration due to gravity on the moon is 1/6 * 9.8 m/s^2 = 1.63 m/s^2.

To find the height the baseball would reach on the surface of the moon, we can use the following equation:

v^2 = u^2 + 2as

Where:
v = final velocity (which is 0 since it comes to a stop at the highest point)
u = initial velocity
a = acceleration due to gravity on the moon
s = height

Since it is thrown upward, the initial velocity is positive. Therefore, we can rearrange the equation to solve for the height:

s = (v^2 - u^2) / (2a)

Substituting the values we know:

s = (0 - u^2) / (2 * 1.63)

Since the initial velocity is not given, we cannot solve for the exact height. However, we can use the same equation to find the maximum height the baseball could reach if thrown upward with a specific initial velocity on the moon's surface.

To find the height the baseball would reach when thrown on the moon, we can use the concept of conserving energy.

First, let's determine the initial velocity of the baseball when it is thrown upwards. Assuming no air resistance, the velocity at the highest point of the baseball's trajectory will be zero. We can find the initial velocity using the equation:

Vf^2 = Vi^2 + 2aΔy,

where Vf is the final velocity (which is zero in this case), Vi is the initial velocity, a is the acceleration due to gravity, and Δy is the change in height.

On earth, the acceleration due to gravity is approximately 9.8 m/s^2, and the change in height is 51 m.

0 = Vi^2 + 2(9.8)(51).

Now, let's solve for Vi:

Vi^2 = -2(9.8)(51),

Vi^2 ≈ -999.6,

Vi ≈ -31.6 m/s (ignoring the negative sign).

So, the initial velocity on earth is approximately 31.6 m/s.

Next, let's find the height the baseball would reach on the moon. Given that the acceleration due to gravity on the moon is one-sixth of that on earth (approximately 9.8 / 6 = 1.63 m/s^2), we can use the same equation:

0 = Vi^2 + 2(1.63)Δy,

0 = (31.6)^2 + 2(1.63)Δy.

Solving for Δy:

2(1.63)Δy = -(31.6)^2,

Δy = -(31.6)^2 / (2 * 1.63),

Δy ≈ -306 m.

The negative sign arises because the initial velocity is upwards. Neglecting the negative sign, we find that the height the baseball would reach on the moon is approximately 306 m.

Therefore, the answer is not 306 m, but 306 m with a negative sign indicating the downward direction.
