An inextensible string is passing over a light frictionless pulley. One end of the string is connected to a block of mass
4m which is resting on a horizontal surface. To another end, a plate of mass
m is attached and is hanging in the air. A particle of mass
m strikes from above with vertical velocity
v0 and sticks to the plate. Calculate maximum height attained by the block of mass
4m.
