A block of mass kg 5 is moving horizontally at a speed of `1.5 m//s` . A perpendicular force of 5 N acts on it for 4 sec. What will be the distance of the block from the point where the force started acting

A block of mass 10 kg is moving horizontally with a speed of 1.5 ms^(-1) on a smooth plane. If a constant vertical force 10N acts on it, the displacement of the block from the point of application of the force at the end of 4 second is

A body of mass 5kg is moving along a circle of radius 1m with a uniform speed of 5m//s . The external force acting on the body is

A block of mass 4 kg is placed on a rough horizontal plane. A time dependent horizontal force F = kt acts on the block (k = 2 N/s). Find the frictional force between the block and the plane at t = 2 second and t = 5 second (mu = 0.2)
