If a ball rolls down an inclined plane and gains 4 m/s each second it rolls,its acceleration is A)one half of 4 m/s. B)one half of 4 m/s². C)4 m/s². D)10 m/s².

Question

Quizplus · Accepted Answer

Acceleration = (change in velocity) / (time taken)
Here, the velocity is changing by 4 m/s every second, so the time taken is 1 second.

Therefore, acceleration = (4 m/s) / (1 s) = 4 m/s^2.

The correct option is Choice letter C.
