Applying Newton's Laws Problem 1: A 75.0-kg wrecking ball hangs from a uniform, heavy-duty chain of mass 26.0 kg. (a)Find the maximum and minimum tensions in the chain. (b) What is the tension at a point three-fourths of the way up from the bottom of the chain?

Problem 2: A 1130-kg car is held in place by a light cable on a very smooth (frictionless) ramp(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?
