Question

A ball was rolling at a velocity of 15 m/s. After 5 seconds, its velocity is measured to be 60m/s, what is the acceleration for the dropped ball?

Answer 1

To calculate the acceleration of the ball, we can use the formula:

acceleration (a) = (final velocity (v) - initial velocity (u)) / time (t)

Given: Initial velocity (u) = 15 m/s Final velocity (v) = 60 m/s Time (t) = 5 s

Using the formula, we can substitute the given values:

a = (60 m/s - 15 m/s) / 5 s

Simplifying the equation:

a = 45 m/s / 5 s

a = 9 m/s²

Therefore, the acceleration of the ball is 9 m/s².
