A T rex did 107,000 Joules of work to lift up its prey, a hadrosaur, that has 2721kg of mass. (The force of the hadrosaur is its mass x the acceleration of gravity (9.8m/s^2)).Therefore, how high up did the T rex raise the hadrosaur? (2 points)Group of answer choices3.0m2.7m4.0m2.5m

Amerry-go-round of radius r, shown in the figure, is rotating at constant angular speed. the friction in its bearings is so small that it can be ignored. a sandbag of mass m is dropped onto the merry-go-round, at a position designated by r. the sandbag does not slip or roll upon contact with the merry-go-round. how would you rank the following different combinations of m and r on the basis of the angular speed of the merry-go-round after the sandbag "sticks" to the merry-go-round from largest to smallest. a) m = 10kg, r = 0.25r b) m = 20kg, r = 0.25r c) m = 10kg, r = 0.50r d) m = 10kg, r = 1.0r e) m = 15kg, r = 0.75r f) m = 40kg, r = 0.25r
