    Explanation:

    Consider the elastic head-on collision between a sledge hammer with 2000 g mass and a golf ball with a 5 g mass. The initial velocity of the sledge hammer is 16 m/s, and the golf ball is initially at rest. the concluding part of this question could be:

    this is an elastic collision

    we know from the principles of linear momentum that the total momentum before collision must be equal to total linear momentum after collision

    momentum is the product of mass and its velocity

    m1u1+m2u2=m1v1+m2v2

    m1=2000g mass of the sledge hammer

    u1=16m/s initial velocity of the sledge hammer

    m2=5g mass of the golf ball

    u2=0 velocity of the golf ball

    v1=0m/s final velocity of the sledge hammer

    v2=? final velocity of the golf ball

    2000*16+5*0=2000*0+5v2

    v2=2000*16/5

    v2=400*16

    v2=6400 m/s
