Question

two balls having mass 100g in 200g are moving in same direction with velocity 3m/s and 2m/s respectively they collide with each other and after collision the first ball moves with velocity 2m/s calculate the velocity of the other ball​

Answer 1

Answer:

1=100g=0.1kg

m2=200g=0.2kg

u1=1m/s

u2=2m/s

Velocity of first ball after collision(v1)=2m/s

According to law of Conservation of Momentum,

Momentum before Collision=Momentum after Collision

Therefore,Final Velocity of the second ball=1.5m/s

Step-by-step explanation:

using m1u1+m2u2=m1v1+m2u2
