1. The problem statement, all variables and given/known data A force that averages 1200N is applied to a 0.4kg steel ball moving at 14m/s in a collision lasting 27ms. If the force is in a direction opposite the inital velocity of the ball ,find the final speed and direction of the ball 2. Relevant equations n/a 3. The attempt at a solution I used FdeltaT=mv 1200(27x10^-3)=0.4(v2-v1) 32.4=0.4v2-5.6 38/0.4=v2 95m/s =V2. Is this correct?
