A particle starts its motion- at t = 0 along X axis. If the kinetic energy is proportional with time then, show that the force on the body how- changes with time?

How will the momentum of a body change if its kinetic energy is doubled ?

What is the kinetic energy of a rotating body about its axis of rotation ?

A particle of mass m at rest in acted upon by a force P for a time t. its kinetic energy after an interval t is

A particle is excecuting such a motion that its. decceleration is propertional to its displacement, what will be the change of kinetic energy of the body?

A particle is moving in a straight line such that its retardation is directly proportional to its displacement . Decrease in the kinetic energy of the body is directly proportional to

If a particle of charge q is moving with velocity vecv along y axis and a magnetic field vecb act along z axis, find the force acting on it. What happens to its kinetic energy ? Justify.

If the kinetic energy of a body changes by 20% then its momentum would change by-

A partiole is moving in a straight line such that its velocity at time t is proportional to t^(5) . Then its acceleration is proportional to
