Question

A metal ball of mass 2 kg moving with a velocity of 36 km per hour has a head on collision with a stationary ball of mass 3kg if after the collision the two balls move together the loss in kinetic energy due to collision is ​

Answer 1

Answer:we use the formula of m1v1+m1u1=m2v2+m2u2

Explanation:we have to put the given mass in both the m1 and m2 and fill up the velocity v1 we get answer
