Question

A ball rolls down a ramp for 15 seconds. If the initial velocity of the ball was 2.1 m/sec and the final velocity

was 7.3 m/sec, what was the acceleration of the ball?

Answer 1

Answer: a=.347

Explanation: Acceleration can be calculated by subtracting the initial velocity (2.1 m/s) from the final velocity (7.3) and dividing the difference by the time (15s).

`(7.3-2.1)/(15) = .347`
