Question

solve this:(c) Two balls having mass of 100 g and 200 g are moving in the same direction with velocty 3 m/s
and 2 m/s respectively. They collide with each other and after collision the first ball moves with
velocity 2 m/s. Calculate the velocity of the other ball​

Answer 1

Explanation:

hi ,here is your ans

According to the law of conservation of momentum

m1u1+m2u2=m1v1+m2v2

100g=0.1kg

209g=0.2kg

0.1*3+0.2*2=0.1*2+0.2*x

0.3+0.4=0.2+0.2x

0.7-0.2=0.2x

0.5/0.2=x

x=2.5

Hope you got your ans..
