Consider a planet in orbit around a star as depicted below. It begins at position A, goes to B along the orbit and so forth through E. Using Kepler’s laws, rank the positions in terms of planetary speed, slowest to fastestand give a justification. At points A through E, sketch the velocity and acceleration vectors. Determine the acceleration vectors based on the motion of the planet along and without considering forces. Justify your answer to (b) in terms of force.
