Question

Step 1

Let *m* be the mass of the block, *d* be the distance between the uncompressed spring and block, *v* be the velocity of the block, *l* be the length of the uncompressed spring, *x* be the distance by which the spring is compressed, *k* be the spring constant.

Write the given numerical values.

Step 2

Refer the following diagram to analyse the motion of the block and compression of spring.

Step 3

Write the expression for initial kinetic and potential energy of the system. As t...
