A body of mass 2 kg starts with an intitial-velocity 5 m/s. It the body is acted upon by a time dependent force (F) as shown in figure, then work done on the body in 20 s is

A body of mass 1 kg moves with an initial velocity of 15 m/s . If its velocity changes to 25 m/s in 5 seconds, find the force acting on the body.

For body of 50 kg. mass, the velocity time graph is shown in figure. Then force acting on the body is :-

For body of 50 kg. mass, the velocity time graph is shown in figure. Then force acting on the body is :-

For body of 50 kg. mass, the velocity time graph is shown in figure. Then force acting on the body is :-

A body of mass 2kg has an initial speed 5 m/s. A force acts as it for some time in the direction of motion. The force-time graph is shown in figure. Find the final speed of the body.

A body of mass 5kg is acted upon by a variable force. The force varies with the distance covered by the body as shown in figure. What is the speed of the body when it has covered 25m ? Assume that the body starts from rest.

A body acted upon by a variable force F = 3 +0.5.x. Work done in moving the body from x=0 to x = 4m is:
