Question

A moving ball p of mass 100g collides with a stationary ball q of mass 200g after collision p moves backwards with a velocity of 2 m/s while q moves forward with velocity of 5m/s find initial velocity p

Answer 1

Answer:

8m/s

Explanation:

applying Momentum conservation

mv+0= mv1+Mv2

100*v= 100*(-2) +200*5

v= 800/100

v= 8m/s
