Question

B) If an object has 0 momentum,does it have kinetic energy?Explain your answer. Answer....​

Answer 1

Momentum of an object , P = mv 

Momentum of an object , P = mv If  P = 0 

Momentum of an object , P = mv If  P = 0 ⇒ v=0 

Momentum of an object , P = mv If  P = 0 ⇒ v=0 This is because mass of the can never be 0. Now , kinetic energy of the object , K=21× m× v² 

 Since , V = 0 

 Since , V = 0 ⇒ K=0

K=0Hence, when the object has zero momentum, its kinetic energy is also zero.
