Nevermind, I've got it. I didn't convert the weight of the ball to the mass of the ball using the gravitational acceleration. Thanks.

How many foot pounds of work does it take to throw a baseball 90 mph? A baseball weighs 5 oz, or 0.3125 lb. The only equation I can find is W= (change) KE, where KE=1/2mv^2 When I try plugging in the data given I'm not getting the correct answer. I don't know if I'm doing incorrect unit...
