(5%) Problem 10: As a 100-kg object falls toward the Earth in space, the gravitational force is directed toward the Earth and is modeled by the function F(r) = -k / 12, where k is a constant equal to 4.0 x 1016 N.m. R R ©theexpertta.com = A 33% Part (a) Write an equation for the work done by gravity as a 100-kg object falls from a height R, above the earth to a height R2. A 33% Part (b) Calculate the work done by gravity in megajoules (MJ) as the 100-kg object falls from a height R1 = 42000 km to a height R2 = 8700 km. DA 33% Part (c) Calculate the work done by gravity in megajoules (MJ) as the 100-kg object falls from a very large distance (infinity) to a height R2 8700 km Grade Summary W Deductions = = 002 0% Potential 10094 Late Work % 100% Late Potential 100% TT ( 7 8 9 HOME sino cotan() atan cos asino acotan tano acos sinh E 4 5 wao 6 * 1 2 3 Submissions Attempts remaining: (0% per attempt)
