A coach is hitting pop flies to the outfielders. If the baseball (m = 145 g) stays in contact with the bat for 0.04 s and leaves the bat with a speed of 50 m/s, what is the average force acting on the ball?"

**Priscilla**, Friday, February 26, 2010 at 11:02amWrite down all the given then this problem might not be hard.

m of ball = 145 kg

t = 0.04 s

v = 50 m/s

Force(avg) = mass*acceleration(avg)

Also, acceleration(avg) = (delta)velocity/(delta)time, where delta represents change.

Now, solve for these variables:

acceleration(avg) = (50-0)/(.04-0) = 1250 m/s^2. Now calculate avg force:

Force(avg) = (.0145)(1250) = 18.125 N
