Homework Help Forum: High School Physics

Posted by Mia on Wednesday, September 23, 2009 at 7:41pm.

Paleontologists estimate that if a Tyrannosaurus rex were to trip and fall, it would have experienced a force of approximately 260,000 acting on its torso when it hit the ground. Assuming the torso has a mass of 3800 kg, 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 .) Figure out acceleration a and change in time (delta t). What confusing me is I thought since F=ma you would do 260000/3800 it seems to be wrong though. Can anyone help? Mia
