A solid sphere of mass

2 \mathrm{~kg}

is rolling on a frictional horizontal surface with velocity

6 \mathrm{~m} / \mathrm{s}

. It collides on the free end of an ideal spring whose other end in fixed. The maximum compression produced in the spring will be

\sqrt{x} \mathrm{~m}

. Find the value of

x

(Force constant of the spring is

36 \mathrm{~N} / \mathrm{m}

View answer and explanation

Correct option: A

2.8

Option A (2.8) is correct because the maximum compression is found by equating the total kinetic energy (translational and rotational) to the potential energy stored in the spring.
