Miranda, a satellite of Uranus, is shown in part a of the figurebelow. It can be modeled as a sphere of radius 242 km and mass 6.681019 kg.
(a) Find the free-fall acceleration on its surface. (m/s2)
(b) A cliff on Miranda is 5.00 km high. It appears on the limbat the 11 o'clock position in part a of the figure above and ismagnified in part b of the figure above. A devotee of extremesports runs horizontally off the top of the cliff at 8.50 m/s. Forwhat time interval is he in flight? (Ignore the difference in gbetween the lip and base of the cliff.) (s)
(c) How far from the base of the vertical cliff does he strikethe icy surface of Miranda? m (d) What is his vector impactvelocity? (m/s ° below the horizontal)
