Question

A ball, released from rest, takes 4.00s to roll down a straight, 12.0m long, ramp(inclined plane). What is the speed of the ball halfway down the ramp?

Step 1

Given,

Step 2

Let the ball of mass m and the inclination angle is θ. Now, by the conservation of energy and take *D* as a reference point.

Step 3

Initial Kinetic Energy is zero because initially ball was in the rest and f...
