Phys . 1701 Homework 6 1. Jill of the Jungle swings on a vine 6.5 m long. What is the ten- sion in the vine if Jill, whose mass is 61 kg, is moving at 2.4 m/s when the vine is vertical? 2. (a) As you ride on a Ferris wheel, your apparent weight is different at the top and at the bottom. Explain. (b) Calculate your apparent weight at the top and bottom of a Ferris wheel, given that the radius of the wheel is 7.2 m, it completes one revolution every 28 s, and your mass is 55 kg. 4 A Ferris Wheel 3. Driving in your car with a constant speed of 12 m/s, you en- counter a bump in the road that has a circular cross-section, as indicated in Figure 1 . If the radius of curvature of the bump is 35 m, find the apparent weight of a 67-kg person in your car as you pass over the top of the bump. D = 12 m/5 7 = 35 m A FIGURE
