Problem
A ring and a disc are initially at rest, side by side, at the top of an inclined plane which makes an angle 60∘ with the horizontal. They start to roll without slipping at the same instant of time along the shortest path. If the time difference between their reaching the ground is (2−3)/10 s, then the height of the top of the inclined plane, in metres, is _____. Take g=10 ms−2.
