Question

If block A is moving with an acceleration of 5 m/s2, the acceleration of B w.r.t ,ground  is

Options

A.5 m/s2
B.5√2  m/s2
C.5√5  m/s2
D.10  m/s2

Solution

Since A is moving in left direction with 5 m/s2  acceleration, the rope will be loosened at the rate of 10 m/s2 acceleration which will be the rate at which block B will come vertically down.
 Therefore, we have a situation like this: 
For B :
Net acceleration
= m/s2
