Question

Two billiard balls each of mass 0.05 kg moving in opposite directions with speed 6 m collide and rebound with the same speed. What is the impulse imparted to each ball due to the other?

Answer 1

$\huge\bf{Answer:-}$

According to the given question:-

• 0.05 kg is the mass of each ball 6 m/sis the Initial velocity of ball 0.3 kg m/s is the magnitude of the initial momentum.

So, the simple steps:-

=(pi) = 0.3 kg m/s

=(f) = –0.3 kg m/s

= pf – pi

= –0.3 – 0.3 and

= –0.6 kg m/s
