Chapter 5, Problem 75GP
BIO The Fall of T. rex 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?

As a fish jumps vertically out of the water, assume that only two significant forces act on it: an upward force F exerted by the tail fin and the
downward force due to gravity. A record Chinook salmon has a length of 1.50 m and a mass of 45.0 kg. If this fish is moving upward at 3.00 m/s as its
head first breaks the surface and has an upward speed of 5.40 m/s after two-thirds of its length has left the surface, assume constant acceleration and
determine the following.
(a) the salmon's acceleration
m/s² upward
(b) the magnitude of the force F during this interval
