Homework Help: Please help me solve this physic problem

  1. Jan 30, 2010 #1
    A Toyota Vios (m = 1700 kg) is parked on a road that rises 15° above the horizontal. What are the magnitudes of (a) the normal force and (b) the static frictional force that the ground exerts on the tires?

    A problem like this starts with you, the student, drawing a free-body diagram, showing all forces acting on the object.

    Draw the free-body diagram. You won't need the coefficient of friction for this.

    Also, what is the acceleration of the car?
