A) 3 m/s
B) 5 m/s
C) 9 m/s
D) 14 m/s
Correct Answer: D
Solution :
When a particle moves on a circular path with constant speed, then its motion is said to be uniform circular motion in a plane. This motion has an acceleration whose magnitude is constant, but whose direction changes continuously. Since, kinetic energy is the energy possessed by a body due to velocity (v) hence it remains constant. \[K=\frac{1}{2}m{{v}^{2}}\]You need to login to perform this action.
