marks A train starts from rest at t 0 along a straight track with a constant acceleration of 5 m s A passenger at rest in train observes a particle of mass 1 kg on the floor with which it has a coefficient of friction us Uk 0 6 Att s a horizontal force F 13 N is applied on the particle for 2s duration The passenger observes that the particle is now moving in a perpendicular direction of motion of the train g 10 m s 5 1 13 The magnitude of acceleration of the particle with respect to the ground at t 5 sec is 61 m s with the direction of motion of the train The direction in which force F 13 N is applied is at cos The momentum of the particle at t 6 sec with respect to the train is 12 kg m s The momentum of the particle at t 6 sec with respect to the train is 6 kg m s
