1. The problem statement, all variables and given/known data A 0.5kg softball is pitched at a speed of 13m/s. The batter hits it back directly at the pitcher at a speed of 29m/s. The bat acts on the ball for 0.018 s. a)What is the magnitude of the impulse imparted by the bat to the ball? Answer in units of N *s. b) What is the magnitude of the avg force exerted by the bat on the ball? I know there is conservation of momentum. Is there such thing as conservation of impulse? I know impulse is the change in momentum, so I used the formula change in momentum= Force * change in time or = mass* (Vf-Vi) but when i plugged in numbers for the 2nd equation, i got the impulse as 8 Ns, which is wrong. Can someone help me find out where I went wrong?
