Question

A block of mass 10kg is released from rest and slides down a frictionless track of height h 5m above a table (see figure). At the bottom of the track, where the surface is horizontal, the block strikes and sticks to a light spring with spring constant k 10k the acceleration of gravity to be 9.81 The maximum distance d the spring is compressed is

Answer 1
