QuestionA ball rolls down a ramp for 15 seconds, starting at $1 \mathrm{~m/s}$ and ending at $7 \mathrm{~m/s}$. Find its acceleration.

Studdy Solution
Divide the change in velocity by the time to calculate the acceleration.
$$Acceleration = \frac{ \, m/sec}{15 \, sec} =0.4 \, m/sec^2$$The acceleration of the ball was $0.4 \, m/sec^2$.
