The momentum is most closely related to

A body of mass $5 \,kg$ is moving with a momentum of $10\, kg-m/s$. A force of $0.2 \,N$ acts on it in the direction of motion of the body for $10\, seconds$. The increase in its kinetic energy is ............... $J$

In the figure given below, the position-time graph of a particle of mass $0.1 \,Kg$ is shown. The impulse at $t = 2\sec $ is .......... $kg\,m\,{\sec ^{ - 1}}$

Below figure shows the position-time graph of a body of mass $0.04\; kg$. Suggest a suitable physical context for this motion. What is the time between two consecutive impulses received by the body ? What is the magnitude of each impulse ?

In two different experiments, an object of mass $5\; kg$ moving with a speed of $25\; ms ^{-1}$ hits two different walls and comes to rest within

$(i)$ $3$ second, $(ii)$ $5$ seconds, respectively.

Choose the correct option out of the following :

A ball of mass m moves with speed $v$ and it strikes normally with a wall and reflected back normally, if its time of contact with wall is $t$ then find force exerted by ball on wall
