Solve the given parts of following problem:Problem: Assume the Earth's orbit around the sun is a circle and has radius 1.50 x 108 km. This is a rough approximation of the Earth's true elliptical orbit.
Part A: What is the magnitude of the orbital velocity of the Earth in m/s?
Part B: What is the radial acceleration of the earth toward the sun, in m/s2?
Part C: Repeat parts a) and b) for the planet Mercury (orbital radius 5.79 x 107 km; orbital period 88.0 days).
Any help would be greatly appreciated! Thank you so much!
