1. The problem statement, all variables and given/known data In baseball, a pitcher can accelerate a 0.15 kg ball from rest to 90 mi/h in a distance of 1.6 m. (a) What is the magnitude of the average force exerted on the ball during the pitch? ____N 2. Relevant equations a=d/t xf=xi+vixt+1/2(a)t^2 Fnet=ma 3. The attempt at a solution I know that to find out this problem I need to find out the Fnet. I know that Fnet=ma but how do I find out the a!? I know to figure out acceleration its distance/time but.. How do I figure out acceleration? This is getting really frustrating. It gets to 90 mi/hr in 1.6m. Does mass have anything to do with finding out the acceleration? Please help!
