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.

  • Physics -

    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.

  • Physics -

    star mark stands for what

  • Physics -

    * means multiplication (x)

  • Physics -

    10*30=(10+15)*V2

    300/25 =25V2/25

    V2=12m/s
