Homework Help: Ap Physics

Posted by Tiffany on Thursday, September 24, 2009 at 2:05am.

Paleontologists estimate that if a Tyrannosaurus rex were to trip and fall, it would have experienced a force of approximately 260,000N acting on its torso when it hit the ground.

Assuming the torso has a mass of 3800kg , 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 .)

a=?

Assuming the torso is in free fall for a distance of 1.21m as it falls to the ground, how much time is required for the torso to come to rest once it contacts the ground?

delta t (change in t)=?

i've tried everything i wanna cry?
