Paleontologists estimate that if a Tyrannosaurus rex were to trip and fall, it would have experienced a net force of approximately 261,200 N acting on its torso when it hit the ground. Suppose the torso has a mass of 3730 kilogram.
(a) Calculate the magnitude of the torso upward acceleration as it comes to rest. (For comparison, humans lose consciousness with an acceleration of about 7g)
(b) Suppose the torso is in free fall for a distance 1.61 meter as it falls to the ground, find how much time is required for the torso to come to rest once it contacts the ground?
two identical capacitors store different amounts of energy capacitor a stores 2.4 x 10-3 j and capacitor b stores 6.7 x
When the pressure on saturated liquid water is suddenly reduced to a lower pressure in an adiabatic and aergonic process, the liquid's temperature must also be reduced to reach a new equilibrium state.
A football is kicked from the ground towards the end zone, which is 60.0 m away. If the football's initial velocity is 25m/s, directed 41 degrees of the horizontal, will it land in the end zone or fall short? Assume air resistance is negligible. Show..
