A force of 10 N acts on a body of mass 2 kg for 3s , initially at rest. Calculate the velocity acquired by the body

A body is initially at rest on a smooth surface. A force 20 F,whose time variation is shown in the figure acts on it for a duration of 4 s. The momentum of the ball at the end of the 4 s (Ns) is

Power of a force acting on a block varies with time t as shown in figure. Then, angle between force acting on the block and its velocity is

Power of a force acting on a block varies with time t as shown in figure. Then, angle between force acting on the block and its velocity is

A force given by the relation F = 8t, (F in Newton and t in sec.) acts on a body of mass 2kg. Initially at rest. Choose the correct option.

A force given by the relation F = 8t, acts on a body of mass 2 kg, initially at rest. Find the work done by this force on the body during first 2 seconds of its motion
