... A golfer making a putt gives the ball an initial velocity of v0, but he has badly misjudged the putt, and the ball only travels one-quarter of the distance to the hole. If the resistance force due to the grass is constant, what speed should he have given the ball (from its original position) in orde ...

Thus, the change in momentum (impulse) is greater for the hail. Since Dp = F Dt, more force is required in the hailstorm. This is similar to the situation with the ...
