5.8 .. A 1130-kg car is held in place by a light cable on a very
smooth (frictionless) ramp, as shown in Fig. E5.8. The cable
makes an angle of 31.0° above
the surface of the ramp, and
the ramp itself rises at 25.0°
above the horizontal. (a) Draw
a free-body diagram for the
car. (b) Find the tension in
the cable. (c) How hard does the
surface of the ramp push on the
car?
