The answer to the first part of one of the problems is:(adsbygoogle = window.adsbygoogle || []).push({});

W=F*v*t*cos(theta)

The second asks me to take the time derivative of this equation in order to find the power produced. How do I do this??

Also, say a baseball leaves a pitcher's hand at a speed of v and the mass of the baseball is M_baseball. You can ignore air resistance. What is the work done on the ball by the guy??
