A 2 kg body performs SHM of amplitude 20 cm, and the restoring force acting at that position is 50 N. Find the acceleration and kinetic energy of the particle when the displacement is 10 cm.
A) Acceleration: 25 m/s², Kinetic energy: 10 J
B) Acceleration: 10 m/s², Kinetic energy: 5 J
C) Acceleration: 5 m/s², Kinetic energy: 10 J
D) Acceleration: 10 m/s², Kinetic energy: 10 J
