A body of mass 10kg moving with velocity 30m/s collide with another body of mass 15kg.If the velocity of both the body are same after collision.Then find their common velocity.

Answer 1

The law of conservation of linear momentum will allow you to solve this problem. They apparently want you to assume that the 15 kg body is initially stationary.

M1*V1 = (M1 + M2)*V2
M1 = 10 kg
M2 = 15 kg
V1 = 30 m/s
Solve for V2.

Answer 2

star mark stands for what

Answer 3

* means multiplication (x)

Answer 4

10*30=(10+15)*V2

300/25 =25V2/25

V2=12m/s
