Question 21

A calibration trolley of mass M M\,M on a frictionless track is attached to a spring of stiffness kkk. The trolley is displaced by a distance X X\,X from its equilibrium position and released from rest, oscillating with simple harmonic motion. The maximum kinetic energy of the trolley during this oscillation is EkE_kEk​.

The setup is then altered:

  • The trolley's mass is increased to 3M3M3M.
  • The spring is replaced with one of stiffness 2k2k2k.
  • The trolley is displaced by a distance 2X 2X\,2X from its equilibrium position and released from rest.

What is the maximum kinetic energy of the trolley in this new oscillation?

A

4Ek4E_k4Ek​

B

8Ek8E_k8Ek​

C

12Ek12E_k12Ek​

D

24Ek24E_k24Ek​
