1. The problem statement, all variables and given/known data A golf ball with a mass of 43.80 g can be blasted from rest to a speed of 64.60 m/s during impact with a club head. Assume that the impact lasts only about 0.980 ms. Calculate the change in momentum of the ball. 2. Relevant equations P = mv Change in P = Pf - Pi J = 1/2 base * height Favg = J/Change in time 3. The attempt at a solution Mg = .04380kg Vi = 0m/s Vf = 64.60m/s Time = .00098s A.) Change in P = (.04380kg * 64.60m/s) - (.04380kg - 0m/s) = 2.83kg*m/s RIGHT B.) J = 1/2 * 0.00098s * 2.83kg*m/s = .001386 Favg = (0.001386N/s)/(0.00098s) = 1.415N WRONG...But I don't know why. I think it has to do with when I calculated J I am not sure if my height (Fmax) is supposed to be the 2.83kg*m/s.
