Question:

Paleontologists estimate that if a Tyrannosaurus rex had tripped and fallen, the ground would have exerted a normal force of approximately 260,000 N on its torso as it landed. Assuming the torso has a mass of 3800 kg,
(a) Find the magnitude of the torso's upward acceleration as it comes to rest. (For comparison, humans lose consciousness with an acceleration of about 7g.)
(b) Assuming the torso of a T. rex is in free fall for a distance of 1.46 m as it falls to the ground, how much time is required for the torso to come to rest once it contacts the ground?
