A system of two blocks and a light string are kept on two inclined force (rough) as shown in figure All the are mentioned in the diagram pulley is light and frictionless `(Take g = 10ms^(-2) , sin 37^(@) = 3//5)`

In the above question the motion of the system would be best described by

Options

A. The system first decelerates, comes to a stop, and then continues s to move in the opposite direction
B. The system will continuously move with constant speed
C. The system first decelerates and than come to a stop
D. The system acceleration and its speed increases with time

Answer

C

Explanation

Once the block comes to rest kinetic friction diagram and static friction comes on the existence and then situation would be identical to that of Q68
