Homework Help: Frictional Force

  1. Sep 13, 2005 #1
    Okay, I have tried this problem 13 times, used up 13 sheets of paper and I just don't know how to do this. Do ask me what I don't know, because I just don't understand physics, and no one I have asked can explain it to me in a way that I can understand it. Please I hope someone can expain how to set this up and find my answer.

    You are sitting in a stopped car on a hill that is inclined at an angle of 52.7o with respect to the vertical. The combined mass of you and the car is 4270 kg.

    You push down on the gas pedal and begin to travel up the hill. After 17.3 s have elapsed, your height has increased by 194 m.

    Assuming that the frictional force was constant as you drove up the hill, what was the magnitude of the frictional force from the road on the car's tires?
