Two billiard balls each of mass 0.05 kg moving in opposite directions

1.	Two billiard balls each of mass 0.05 kg moving in opposite directions with speed 6 m s-1 collide and rebound with the same speed.What is the impulse imparted to each bail due to the other?
Answer» Given: m = 0.05 kg. u = 6 m/s, v = -6 m/s To find: Impulse (J) Formula: J = m (v – u) Calculation: From formula, J = 0.05 (-6 – 6) = -0.6 kg m s^-1 Impulse received by each ball is -0.6 kg m s^-1.

Answer»

Given: m = 0.05 kg. u = 6 m/s, v = -6 m/s

To find: Impulse (J)

Formula: J = m (v – u)

Calculation: From formula,

J = 0.05 (-6 – 6) = -0.6 kg m s^-1

Impulse received by each ball is -0.6 kg m s^-1.
