Example Problems

Problem 1
A 2155 kg demolition ball swings at the end of a 17.5 m cable on the arc of a vertical circle. At the lowest point of the swing, the ball is moving at 8.6 m/s. Determine the tension in the cable at the lowest point. (Solutions)

Problem 2
A motorcycle is traveling up one side of a hill and down the other side. The crest is a circular arc with a radius of 45.0 m. Determine the maximum speed that the cycle can have while moving over the crest without losing contact. (Solutions)
