Hi there, just a student trying to get some help on circular motion problems in physics. Could definitely use the support thank you so much (:

1. What provides the centripetal force that keeps a satellite in orbit? 2. An earth satellite is in a circular orbit with a radius of 7.19x10 m. What is the satellite's speed? a. What is the period of the satellite? b. What is the frequency of the satellite? 3. A person has a mass of 60 kg. What will they weigh on a planet with double the mass of the earth but 3 times the radius?A 25 kg child on a swing that is 1.8 m long is moving at 2.3 m/s through the lowest point in the swing. A) What is the tension in the string at that point? B) What is the centripetal acceleration? 5. A tennis ball with a mass of 0.05 kg is swung in a 0.75 m radius vertical circle. A) What is the tension in the rope at the lowest point of the circle when the ball is going 4.7 m/s? B) What is the tension in the rope at the highest point of the circle when the ball is going only 3.6 m/s? 6. A motorcycle has a constant speed of 25.0 m/s as it passes over the top of a hill whose radius of curvature is 126 m. The mass of the motorcycle and driver is 342 kg. Find the magnitude of the normal force that acts on the cycle
