Question

the object with zero momentuan havo zero Kinetic
energy​

Answer 1

Answer:

No, it would not have kinetic energy.

Linear momentum is given as the product of mass and velocity:

p=mv

If the momentum  p  is zero, then that would require velocity  v  to also be zero.

Linear kinetic energy is given by:

KE=12mv2

As such, if  v  is zero, kinetic energy is also zero.

It is the same case with angular momentum and angular kinetic energy. Angular momentum is given by

L=Iω

If the angular momentum  L  is equal to zero, then the angular velocity  ω  must also be zero as  I  is merely a product of mass and radius/length.

Angular kinetic energy is given by

KEA=12Iω2

Similarly to its linear counterpart, if  ω  is zero, angular kinetic energy is also zero.

Answer 2

Answer:

velocity is zero(0).Since ,the velocity is 0we can infer that the object is at rest .we know that ,kinetic energy is the energy possessed by the body when it is motion .there fore ,we can conclude that an object having 0 momentum would have 0 kinetic energy
