Question

Two blocks A and B each of mass m are hanging stationary by a light inextensible and perfectly inelastic string passing over a light and frictionless pulley, as shown in figure. A particle C of mass moving vertically upwards collides with block B at and gets stuck to it. Velocity of C just before collision is 60 m/s. Find the time (in sec) at which the block B comes to rest first time after the collision with C. ​
