"Momentum is the product of velocity and its magnitude." Is this statement true or false?

$A$ woman throws an object of mass $500\,g$ with a speed of $25\,ms^{-1}$.
$(a)$ What is the impulse imparted to the object?
$(b)$ If the object hits a wall and rebounds with half the original speed,what is the change in momentum of the object?

Five objects of different masses are simultaneously released vertically downwards from height $h$ (in air). Which physical quantity associated with the objects will change at the instant they strike the ground? (Neglect the air resistance.)

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
$(i)$ $3 \; s$,$(ii)$ $5 \; s$,respectively.
Choose the correct option out of the following:

State and explain Newton's third law of motion. Write the important points of Newton's third law of motion.

$A$ $140\,g$ ball,in horizontal flight with a speed of $39.0\,m/s$,is struck by a bat. After leaving the bat,the ball travels in the opposite direction with a speed of $39.0\,m/s$. If the impact time $\Delta t$ for the ball-bat collision is $1.20\,ms$,calculate the average force in $N$ acting on the ball.
