1200-kg car is being towed up an 18° incline by means of a rope
attached to the rear of a truck. The rope makes an angle of 27°
with the incline.
What is the greatest distance that the car can
be towed in the first 7.5 s starting from rest if the rope has a
breaking strength of 4.6 kN?
Ignore all resistive forces on the car. See the figure below:
