Miranda, a satellite of Uranus, is shown in part a of the figure below. It can be modeled as a sphere of radius 242 km and mass 6.68 x 1019 kg. (a) (b) (a) Find the free-fall acceleration on its surface. 0.0761 m/s? (b) A cliff on Miranda is 5.00 km high. It appears on the limb at the 11 o'clock position in part a of the figure above and is magnified in part (b) of the figure above. A devotee of extreme sports runs horizontally off the top of the cliff at 8.40 m/s. For what time interval is he in flight? (Ignore the difference in g between the lip and base of the cliff.) 14.85 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. s (c) How far from the base of the vertical cliff does he strike the icy surface of Miranda? 1815 Your response differs from the correct answer by more than 10%. Double check your calculations. m (d) What is his vector impact velocity? 28.6 m/s 343.63 Your response differs from the correct answer by more than 100%. below the horizontal
