1. The problem statement, all variables and given/known data A 125g ball is thrown with a force of 85.0 N that acts through a distance of 78.0cm. The ball's velocity just before it is caught is 9.84m/s. Calculate the work done on the ball. 2. Relevant equations W= F X d (delta displacement) 3. The attempt at a solution W = 85N X 0.78m = 66.3 J But the answer in my physics textbook is 6.24 J. Can anyone please tell me what I am doing wrong?
