Circular Motion Review Problems 1. A children's carousel rotates 3 times every 2 seconds. The diameter of the carousel is 3.0 meters. a. What is the period of motion? 2. When traveling down the road at a constant speed of 55 mph, 26.4 m/s, the tangential velocity of the wheels is also 55 mph. If a car tire is 65.0 cm in diameter, then; a. What is the period and frequency of the spinning car tire? 3. Given that the Earth is 1.49x10 4. Do the same thing for the Moon: Given it is 3.8x10 5. Given the Earth has a mass of 5.98x10 6. A bicycle wheel of radius 0.325 m rotates at a speed of 10.0 m/s (22.4 mph). 7. The time shaft ride at King's Dominion has a radius of 5.0 m and spins with a period of 1.3 seconds (only a guess). 34. While playing "Bolo Master of the World" little Lisa was spinning a rock around her head on a string 1.32 m long. The rock travels around once every 1.43 seconds. |
