In the figure shown, the forces are acting simultaneously on the body of mass $10\text{kg}$ which is initially at rest. Find its velocity after $10\text{s}$.

Q. A ball of mass $10\text{kg}$ initially at rest starts moving under the influence of a constant force $50\text{N}$. Ball covers $10\text{m}$ before colliding a heavy wall which is moving towards the ball with speed $10\text{m/s}$ as shown in figure. If force stops acting on ball just before collision and collision is perfectly elastic, find the velocity of ball after collision.

Q. In the figure shown, the forces are acting simultaneously on the body of mass $10\text{kg}$ which is initially at rest. Find its velocity after $10\text{s}$.

Q. A large body of mass 100 kg moving with a velocity of 10.0 m/s collides elastically with a small body of mass 100 g at rest. The velocity of the small body, after collision, is.

Q. A body of mass $5\text{kg}$ is acted upon by a variable force which varies with the displacement of the body as shown in figure. What is the speed of the body when it has covered $25\text{m}$? (Assume that the body starts from rest.)

Q. A unidirectional force F varying with time t as shown in the figure acts on a body of mass 1 kg initially at rest, for a short duration 0.2 sec. Then the velocity acquired by the body is
