In the figure shown the block B moves down with a velocity 10m/*. The velocity of A in the position shown is :
(A) 12.5m/*
(B) 25m/*
(C) 6.25m/*
(D) none of these
(B) The velocity of A is 25m/*.
Velocity of string is twice the velocity of B
To calculate, velocity of A as function of velocity of string, use following equation
