At the moment t = 0 a stationary particle of mass m experiences a time-dependent force `F = kt(t'-t)`,where is a constant vector, t' is the time during which the given force acts. Find :
(a) The momentum of the particle when the action of the force discontinued,
(b) The distance covered by particle while the force acted.

Answer

`[kt^(3)//6,dt=(kt^(4))/(12m)]`
