Answer 1

Answer:

without sliding on a horizontal surface. It collides with a light spring of stiffness K with a kinetic energyA sphere of mass m and radius R rolls without sliding on a horizontal surface. It collides with a light spring of stiffness K with a kinetic energy E. If the surface (AB) under the spring is smooth and E = 7J and K = 10 N/m, find the maximum compression of the spring.
