1. The problem statement, all variables and given/known data A soccer player, kicking a soccer ball, gives the ball a velocity of +26.8 m/s. The mass of the ball is 0.425 kg, and the duration of the impact is 1.05 10–3 s. a) What is the momentum of the soccer ball after it has been hit? b) What is the change in momentum of the ball? c) What is the impulse imparted to the ball? 2. Relevant equations P = mv (F*t)=P = mvf = mvi 3. The attempt at a solution a) p = mv p = (0.425kg)(26.8m/s) p = 11.4 kg(m/s) b) (F*t)=P = mvf = mvi = (0.425)(26.8) - (0.425)(0m/s) c) this questions makes me unpleasant, I thought the change in momentum is same as impulse imparted to the ball. What's the difference between b) and c) ?
