The momentum is most closely related to

Force

Impulse

Power

K.E.

Solution

(b) Force is defined as the rate of change of momentum. It is given by $\frac{\text { change of momentum }}{\text { time }}$

Impulse is defined as the change of momentum. It is given by Force $\times$ time. Kinetic energy is the energy possessed by an object because of its motion. It is given by $\frac{1}{2} m v^{2} .$ It can't be calculated by momentum alone. Power is the rate of work done with respect to time. it is not related to momentum. Among force and impulse, There is a lesser calculation for impulse. Also, it has same dimensions as momentum. Hence that is most closely related.

A particle of mass $1\,\, kg$ is acted upon by a force $'F'$ which varies as shown in the figure. If initial velocity of the particle is $10 ms^{^{-1}},$ the maximum velocity attained by the particle during the period is …….. $ms^{-1}$

medium

A bullet is fired from a gun. The force on the bullet is given by:

$F = 600 – 2 \times 10^5\ t$

Where $F$ is in newton and $t$ in second. The force on the bullet becomes zero as soon as it leaves the barrel. What is the average impulse imparted to the bullet?

A $40\ g$ ball dropped from a certain height bounces back from the horizontal ground without losing mechanical energy. If its speed is $10\ m/s$ just before making contact with the ground, and the average value of the force of the ground on the ball is equal to $16\ N$ while ball and wall are in contact, how long were they in contact ………. $s$
