1. The problem statement, all variables and given/known data How to find deceleration of a ball that is hit, given the ball: mass=0.1kg F=20N is hit by a bat for 0.01s has an acceleration of 200ms^-2 when hit by bat speed=2m per sec travels 0.01m as it is being hit by the bat Was initially at rest. 2. Relevant equations a=(v-u)/t 3. The attempt at a solution Using the acceleration formula, I had swapped the positions of u and t, resulting in -200ms^-2, which is wrong. The answer is 2ms^-2, and I am not sure how to go about this. Please help me in getting this qu started!! Thank you!!
