1. The problem statement, all variables and given/known data A girl (starting from rest) is pushing a cart full of softballs at an angle of 30 degrees above the horizontal. She pushes with a force of 150N. She travels through the school store for 20 minutes and travels a total of 800meters. a). How much work (in joules) does she do? b). What is average power (in watts) over the entire time? 2. Relevant equations W=Fdcos(theta), P=W/t, W=J/s 3. The attempt at a solution For part a) I did W=Fdcos(theta) and got 103,923J and for part b) I'm not sure how to write the units because it is in minutes so I just converted 20 minutes to 1200 seconds and got 87 watts, I just don't think I did everything correct because of the large numbers and the units have confused me.
