On an object of mass 1 kg moving along x-axis with constant speed 8 m/s a constant force 2 N is applied in positive y-direction. Find its speed after 4 seconds

A body of mass 10 kg is kept on ground.A vertically upwards force F=20t N,where t is the time in seconds,starts acting on it at t=0.The height of the block from ground at t=10 sec is n*25/3,where n is a constant.Find n.

A monkey of mass m climbs a rope slung over a light frictionless pulley.The opposite end of the rope is tied to a block of Mass M lying on a smooth horizontal plane.Find the acceleration of the block and tension in the rope in the following cases 1)the monkey moves up with an acceleration 'a"...

A container of mass 200 kg rests on the back of an open truck. If the truck accelerates t 1.5 m/sec2, what is the minimum coefficient of static friction between the container and bed of the track required to prevent the container from the sliding off the back of the truck.

A train is travelling up a 3.73 degree incline at a speed of 3.25 metres per second, when the last cart breaks free and begins to coast without friction. (I) How long does it take for the last cart to come to rest momentarily (ii) How far did the last cart travel before (momentarily) coming to...
