- Needs Complete solution with 100 % accuracy.10.What equation can we use to describe the magnitude of centripetal force How does this relate to the equation for centripetal acceleration?14. An object is swung around on a string in a vertical circle, while its speed is slowly increased. At some point, the string breaks. Where in the object's path would this most likely happen? Explain.
- A mass attached to a string is twirled overhead in a horizontal circle of radius R every 0.3 s. The path is directly 2 m above the ground. When released, the mass lands 14.6 m away. a) Draw a sketch of the scenario to include the circular spin and horizontal launch. b) What was the velocity of the mass when it was released and c) What was the radius of the circular path. d) Look closely at the picture and estimate the radius of the overhead circular spin.

- Learning Goal: To find some of the parameters characterizing an object moving in a circular orbit. The motivation for Isaac Newton to discover his laws of motion was to explain the properties of planetary orbits that were observed by Tycho Brahe and analyzed by Johannes Kepler. A good starting point for understanding this (as well as the speed of the space shuttle and the height of geostationary satellites) is the simplest orbit: a circular one. This problem concerns the properties of circular orbits for a satellite orbiting a planet of mass M. For all parts of this problem, where appropriate, use G for the universal gravitational constant. Part A Find the orbital speed v of a satellite in a circular orbit of radius R around a planet of mass M. Express the orbital speed in terms of G, M, and R. ► View Available Hint(s) V = Submit Part B K = Find the kinetic energy K of a satellite with mass m in a circular orbit of radius R around a planet of mass M. Express your answer in terms of m,…Help with 15. Thank you.14 A 1 kg ball is tied to the end of a rope and spun around in a vertical circle.
