Question

the body of mass 5 kg moving in a velocity of 6 m s - 1 collides with another body of the mass 2kg which is at rest afterwards they move in the same direction as before if the velocity of the body mass 2 kg is 2 MS - 1 find the velocity of kinetic energy of a body of mass 5 kg??​

Answer 1

Answer:

67.6 joule

Explanation:

firstly we will find velocity of 5 kg mass by law of conservation of momentum then kinetic energy by 1/2mv^2
