SOMEONE PLEASE HELP ASAP!
Shortly after the 2014 AFC Championship game between the New England Patriots and the Indianapolis Colts, the Patriots were accused of deflating the game balls in order to make them softer and thus easier to catch and throw. The Patriots claimed that any decrease in the pressure of the footballs was due to a decrease in temperature during the game. Is the Patriots’ claim scientifically valid? AKS 5b
A.
Yes because as the temperature of a gas decreases, pressure decreases.

B.
Yes because as the temperature of a gas decreases, the pressure increases.

C.
No because as the temperature of a gas decreases, pressure decreases.

D.
No because as the temperature of a gas decreases, the pressure increases.

Askydiver weighing 140 lb (including equipment) falls vertically downward from an altitude of 19,000 ft and opens the parachute after 18 s of free fall. assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.55|v| when the parachute is closed and is of magnitude 14|v| when the parachute is open, where the velocity v is measured in ft/s. assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is the product of mass and gravitational acceleration. (a) find the speed of the skydiver when the parachute opens. (b) find the distance fallen before the parachute opens. (c) what is the limiting velocity vl after the parachute opens? (d) determine how long the sky diver is in the air after the parachute opens. (e) plot the graph of velocity versus time from the beginning of the fall until the skydiver reaches the ground.
