Question

The rotating systems shown in Fig. 10-1 differ only in that the two identical movable masses are positioned a distance r from the axis of rotation (left), or a distance r/2 from the axis of rotation (right). If you release the hanging blocks simultaneously from rest, and calltL the time taken by the block on the left and tR the time taken by the block on the right to reach the bottom, respectively, then

answer choices are:a

A) tL=tR ,  B) tL=4tR,  C) tL=(squareroot of 2)tR, D) tL=2tR, E) tL = 1/2 tR

Explanation / Answer

a. is the right answer as there is no dependance on the radius and there is no accnin x-component sowe will have same time of flight for same height
