Block A is dropped from a height of 2 m.A second identical block B slides frictionlessly down a ramp of height 2 m inclined at 30 $\circ$ .A third identical block C slides down a frictionless ramp of height 2 m inclined at 45 $\circ$ .Which block is travelling fastest at the bottom of the ramp?

Question

Quizplus · Accepted Answer

The speed at the bottom of the ramp depends only on the height of the ramp and not on the angle of inclination or whether the block is dropped vertically. Therefore, all the blocks will reach the same speed at the bottom, and the answer is D.
