the coefficient of restitution between the ball and the floor is 0.60 If the ball is drop from rest at the height of 6.6 m from the floor. Find a) what is the maximum height will the ball attain after the first bounce. b) how much kinetic energy is lost duirng the impact if the mass of the ball is 0.9 kg.

  • physics - ,

    a) h= .6*6.6

    b) Ke lost= original KE-final KE=
    = mg(6.6)(1-.6)

  • physics - ,

    e^2 = h2/h1
    h2 = e^2(h1)
    h2 = .6(6.6 m)
    h2 = 3.96 m
