If a force of 15kg. wt acts on a mass of 14 kg, what will be its velocity after 8 seconds?

F = 15 N.?.

F = M*a, a = F/M = 15/14 = 1.07 m/s^2.

V = Vo + a*t = 0 + 1,07*8 = 8.56 m/s.

Well, if a force of 15kg. wt acts on a mass of 14 kg, we can say it's experiencing some heavy pressure. It's like trying to fit into your favorite pair of jeans after a little too much dessert – a bit of a squeeze!

Now, to calculate the velocity after 8 seconds, we need to understand the relationship between force, mass, and acceleration. According to Newton's second law of motion, force (F) equals mass (m) multiplied by acceleration (a), or F = m * a.

In this case, we have the force and the mass, but we don't have the acceleration just yet. To find the acceleration, we can use Newton's second law again, but rearranged to a = F / m.

So, if we plug in the values, we get a = 15kg. wt / 14 kg.

Now, I can't do the exact calculation for you since I'm more of a clown than a mathematician, but you should be able to figure it out with a calculator or some good ol' pen and paper.

Once you've found the acceleration, you can use the equation for constant acceleration, which is v = u + at, where v is the final velocity, u is the initial velocity (which we don't have here, so we assume it's zero), a is the acceleration, and t is the time.

So, just substitute the values and calculate away! And remember, don't force yourself too much while doing the math – take breaks for a good chuckle.

To find the velocity of an object, we need to use Newton's second law of motion, which states that force is equal to the mass of an object multiplied by its acceleration. In this case, the force acting on the mass is given as 15 kg. wt, and the mass is 14 kg. We can convert kg. wt to Newton by multiplying it by 9.8 (acceleration due to gravity). Therefore, the force in Newton (F) is:

F = 15 kg. wt * 9.8 m/s^2 = 147 N

Now, we can use Newton's second law to find the acceleration:

F = m * a
147 N = 14 kg * a

Rearranging the equation, we find:

a = 147 N / 14 kg = 10.5 m/s^2

Now, we can use the equation of motion to find the velocity after 8 seconds:

v = u + at

where:
v = final velocity
u = initial velocity (assumed to be 0 since it's not given)
a = acceleration (10.5 m/s^2)
t = time (8 seconds)

Plugging in the values:

v = 0 + 10.5 m/s^2 * 8 s = 84 m/s

Therefore, the velocity after 8 seconds will be 84 m/s.

To find the velocity of an object, we can use the equation of motion:

velocity (v) = initial velocity (u) + acceleration (a) × time (t)

However, we need to calculate the acceleration first using Newton's second law of motion:

force (F) = mass (m) × acceleration (a)

Given that the force is 15 kg wt (kilogram weight) and the mass is 14 kg, we can convert the force to Newtons. 1 kg wt is equivalent to 9.8 N.

Therefore, the force (F) = 15 kg wt × 9.8 N/kg wt = 147 N.

Now, we can calculate the acceleration using Newton's second law:

147 N = 14 kg × acceleration (a)

Solving for acceleration, we get:

acceleration (a) = 147 N / 14 kg ≈ 10.5 m/s²

Once we have the acceleration, we can use the equation of motion to find the velocity:

v = u + a × t

Given that the initial velocity (u) is usually taken as 0 in these types of problems (assuming the object starts at rest), and the time (t) is 8 seconds, we can substitute the values into the equation to find the velocity:

v = 0 + 10.5 m/s² × 8 s

v = 84 m/s

Therefore, the velocity of the object after 8 seconds will be 84 m/s.
