Physics An intergalactic spaceship arrives at a distant planet that rotates on its axis with a period of T = 43 hours. The mass of the planet is M = 2.7 • 1025 kg. The spaceship enters a circular orbit with an orbital period that is equal to the planet's period for the rotation about its axis, T. Part a) Write an expression for the radius of the spaceship’s orbit R=? Part b) Calculate the orbital radius in meters

A circus motorcycle acrobat is trying to calculate the speed required to perform a loop- the-loop with a motorcycle. The loop has a radius of 10 m. At what speed must the motorcycle enter the loop at the bottom to negotiate a complete loop against gravity, without the use of its engine while in the loop? We do not have enough information. Mass is required. b) More than 20 m/s. c) More than 25 m/s. Exactly 20 m/s. Exactly 25 m/s.
