Two ends of an inextensible string passing over two fixed pulleys with midpoint connected to a block are pulled down with constant speed ve making the block to move up. Then which of the following options is correct?
A) $v_m = v_e $
B) $v_m > v_e $
C) $v_m < v_e $
D) Data is insufficient to conclude

A small block slides down on a smooth inclined plane, starting from rest at time t = 0. Let $S_n$ be the distance travelled by the block in the interval t = n-1 to t = n. Then, the ratio $\frac {S_n}{S_{n+1}}$ is:
(1) $\frac {2n-1}{2n}$
(2) $\frac {2n-1}{2n+1}$
(3) $\frac {2n+1}{2n-1}$
(4) $\frac {2n}{2n-1}$ Continue reading A small block slides down on a smooth inclined plane ….
