Question: A truck of mass 7912 kg moving at a speed of 60.2 mph has lost its brakes. Fortunately, the driver finds a runaway lane, a gravel-covered incline that uses friction to stop a truck in such a situation; see the figure. In this case, the incline makes an angle of θ = 31.65° with the horizontal and the gravel has a coefficient of friction of 0.634 with the tires of the truck.
Part A: How far along the incline (delta x) does the truck travel before it stops?
I need help to find How far along the incline (delta x) does the truck travel before it stops.
