The block A is moving downward with constant velocity v0. Find the velocity of the block B, when the string makes an angle θ with the horizontal. Image related to  
v0
v0 cos θ
v0 / cos θ
v0 sin θ

Solution:

When two objects are connected by a string component of velocity along the string remains equal.

v1 cosθ = v 0

⇒v1= v0/ cosθ
