gravitational potential energy function U(r) is shown for a planet with mass M and radius R. a) If a projectile is launched from the surface of the planet with a speed equal to the planets escape speed, how fast is the projectile travelling when it reaches a distance r = ∞ ? b) If a satellite orbiting the planet at an altitude of 2R encounters some friction (i.e. a patch of very thin atmosphere) that decreases its speed, what would you expect to happen to the radius of the satellites orbit, and why would you expect that to happen? (4))
