Open-Response Homework Problem 24.1

QUESTION

Open-Response Homework Problem 24.1(a)[5 pts] Calculate gM, the gravitational acceleration on the surface of Mercury. The mass of Mercury is3.30 × 1023kg and its radius is 2.44 × 106m.(b)[3 pts] Will the gravitational potential approximation ∆U = mgM ∆y for Mercury be accurate over alarger or smaller range of values of ∆y than for the Earth? Justify your answer (do the math).G = 6.67 × 10−11 m3kg · s2me = 5.97 × 1024kgre = 6.38 × 106mmm = 7.35 × 1022kgde,m = 3.85 × 108m
