Use this file to help figure out how to solve the problems, then use the numbers given on the submission page to calculate the answers. Problems: 1. A ball whirls around on the end of a string, moving in a circle at a constant speed of 3.0 m/s. If it experiences an acceleration of 3 m/s, how long (in m) is the string? 2. If the string in the previous problem is replaced by a string 2.40 m long but the acceleration remains unchanged, what is the ball's new speed (in m/s)? 3. A hang glider is traveling at a speed of 11 m/s when it enters a horizontal turn with a radius of 12 m. What is the eration (in m/s?) of the hang glider? 4. If the hang glider from the previous problem (with its pilot) has a mass of 130 kg, what is the centripetal force on the glider (in N)? 5. In the figure above, a 3.00 kg ball is traveling in a circle of radius 1.00 m at a constant speed of 10.0 m/s. What is the tension (in N) in the string? 6. The Earth has a mass of 5.97 * 104 kg and the Sun has a mass of 2.00 * 1030 kg. If they are separated by a distance of 1.50 * 10° km, what is the force (in N) between the Earth and the Sun? (Enter your answer in scientific notation: 1.23E12 means 1.23 * 1012) 7. Repeat the previous problem using centripetal forces.
