A 9000kg freight truck attempts to stop on a gravel paved slope with a coefficient of friction of 0.7. A.) What is the maximum slope the freight truck can sustain without sliding backwards? B.) What is the static friction force between the tires and the road at this maximum angle? C.) If the slope was 15 degrees what is the static friction force between the tires and the road?
