- 1 1. Bob twirls a 0.615 kg mass at a constant speed in a 34.0 cm radius circle at a speed of 1.95 m/s. What is the centripetal acceleration? What force in what direction is he exerting at the top and the bottom
- 2 2. Marlene twirls a 2.50 kg mass in a 62.0 cm radius vertical circle at a constant speed. At the bottom of the circle she needs to exert an upward force of 56.4 N of force. What is the centripetal acceleration? What force in what direction is exerted at the top?
- 3 3. Red Elk twirls a 15.0 kg mass in a 1.50 m radius vertical circle. He is so clever that he can do this at a constant speed. At the top, he is pulling down on the mass with a force of 81.0 N. What is the centripetal acceleration of the mass? What is the force he must exert at the bottom?
- 4 4. At what distance from the center of the Earth is the force of gravity 13.5 N on an 18.0 kg mass?
- 5 5. What is the orbital velocity 2.00x106 m from the center of the moon? What is the period of your motion here?
- 6 6. What is the period of motion at a distance of 1.496x1011 m from the center of the sun? Give it in seconds and in days. (3600 seconds to an hour, 24 hours per day…)
- 7 7. You are orbiting a planet with an orbital radius of 7.34x106 m at a velocity of 7350 m/s. What is the mass of the planet?
