Suppose the mass of ball F is 0.5·kg. What is the impulse delivered to the ball by the floor?

Ball going south at velocity 4 m/s, hits floor and returns north velocity at 1 m/s

  • MATH -

    change in velocity = +1 - (-4) = 5
    impulse = mass * change in velocity = change in momentum = .5*5 = 2.5
