Trouble with question -- Catching a baseball & momentum There are three parts to this question, and I am stuck on the last part. The question reads as follows: a) A pitched ball with a mass of 0.5kg reaches a catchers glove traveling at 35m/s. How much momentum does the ball have? My answer: Momentum = m(v) (0.5)(35) = 17.5 kgm/s b) How much impulse is required to stop the ball? The way I answered this question is that impulse and momentum equal each other when the acceleration is constant, or doesnt change. So I said the impulse equals 17.5 Kgm/s as well. c) If the ball is in contact with the glove for 0.5 before its motion is stopped, how much force is applied to the glove? This is the question I am stuck on. I believe my answer is wrong, but this is the way I answered it: Impulse = F(t) 17.5 Kgm/s = F(0.5) 17.5/0.5 = F = 35 Kgm/s2 I honestly feel like my answer to this third part is wrong. And Im having a really hard time with it.
