A meteoroid is moving towards a planet. It has mass m = 0.18×109 kg and speed v1 = 3.8×107 m/s at distance R1 = 1.6×107 m from the center of the planet. The radius of the planet is R = 0.26×107 m. The mass of the planet is M = 10×1025 kg. There is no air around the planet. a) Enter an expression for the gravitational potential energy PE1 of the meteoroid at R1 in terms of defined quantities and the gravitational constant G. Assume the potential energy is zero at infinity. b) Calculate the value of PE1, in joules. c)Enter an expression for the total energy E1 of the meteoroid at R1 in terms of defined quantities.
