1. An asteroid circles the Sun at a distance equal to 50 times the Earth's distance from the Sun. How many years will it take the asteroid to circle the Sun one time? 2. An object weights 4000 N on planet Alpha. Planet Alpha has 8 times the mass of planet Beta and 4 times the radius of planet Beta. What will the object weight on planet Beta? 3. A 60 kg person is sitting on a bathroom scale while riding on a Ferris Wheel. The Ferris Wheel has a radius of 9 m and the person's speed is 3 m/s. Find the scale reading when the person is at the bottom of the motion. 4. A 40 kg person is sitting on a bathroom scale while riding on a Ferris Wheel. The Ferris Wheel has a radius of 10 m and the person's speed is 5 m/s. Find the scale reading when the person is at the top of the motion. 5. A 0.2 kg ball, attached to a string, is moving in a vertical circle. The radius of the circle is 0.4 m and the speed is 6 m/s when the ball is at the top of its path. What is the tension in the string at this instant?
