A body has a momentum of P initially. Force of F (in Newton) in the direction of momentum acts on it for T seconds after that another force of magnitude 3F opposite to the direction of momentum P acts on it for 3T seconds Now the magnitude of momentum of the body is found to be 3p Now another force F acts on it and brings it to rest The duration in seconds for which this force shall act is
