1. The problem statement, all variables and given/known data What power must a woman expend on a 50 kg wagon that she is pulling up a hill at a speed of 0.40 m/s. The hill makes an angle of 20° with the horizontal and the coefficient of friction is 0.35. <<<this was copied and pasted straight from web ct 2. Relevant equations Fnet=Fp-Ffr P=Fvcostheta p=w/t 3. The attempt at a solution I havent really gotten anywhere I just dont see how I could find power without knowing any time or distance and since the woman is moving at a constant velocity the net force must be zero. right? however I know if an object is moved work is done. and considering there is no distance given I dont see how I could find a time. I have a feeling im missing something very obvious or it is unsolvable. I am stuck and I am in a distance course and my instructor doesnt seem to want to check his email so im getting a bit stressed out whihc as you know tends to cloud the mind this is the last question of my assignment whihc is due tonight please help me.
