1.	A ball of 5kg mass moving to the right at a velocity of 2m/s on a friction less table , collides with a stationary 7.5kg ball.find the final velocity of the balls if the collision is elastic.
Answer» Answer: $m_{1} v_{1} = m_{2} v_{2$ 10 = 7.5 * V2 100/75 = $v_{2$ 20/15 = $v_{2$ $v_{2$ = 4/3 m/s

Answer»

Answer:

$m_{1} v_{1} = m_{2} v_{2$

10 = 7.5 * V2

100/75 = $v_{2$

20/15 = $v_{2$

$v_{2$ = 4/3 m/s
