Question

On his way to deliver presents Santa has a minor accident. If the sleigh (1200 kg) was traveling at 322 m/s and the jet(4800 kg) was traveling at 680 m/s and they collided head on, what was the final velocity of the two objects after the collision

    Answer:

    608.4m/s

    Explanation:

    We are given that

    Mass of Sleigh,M=1200 kg

    Speed of Sleigh,u=322 m/s

    Speed of jet,u’=680 m/s

    Mass of jet,m=4800 kg

    Total mass=M+m=1200+4800=6000 kg

    We have to find the final velocity of the two objects after the collision.

    The collision is inelastic .

    By using law of conservation of momentum

    Mu+mu'=(m+M)v

    Using the formula

    1200\times 322+4800\times 680=6000v

    6000v=3650400

    v=\frac{3650400}{6000}

    v=608.4m/s

    Hence, the final  velocity of two objects after the collision=608.4m/s
