Hope these r correct:
Normal Force≈ 68.5
Frictional Force≈ 20.5
Accel. ≈ 58.5
These are rounded
It is gravity. As a sky diver falls (ignoring air resistance for now) he increases in acceleration due to gravity, or 9.81m/s^2 (Earth's gravitational acceleration). Inertia is, by definition, <span>a
property of matter by which it continues in its existing state of rest
or uniform motion in a straight line, unless that state is changed by an
external force (credit to Google). However, if the sky diver has some kind of webbing on his suit, a drag force opposite to gravitational weight cancels it, and it moves at a constant drag velocity.
Sorry I got carried away... physicist...

From gas equations
PV/T = Constant
Then
P1V1/T1 = P2V2/T2, but V1 = V2
Therefore,
P1/T1 = P2/T2
P2 = (P1T2)/T1
P1 = 40 psi
T1 = 60°F = 288.706 K
T2 = 90°F = 305.372 K
Substituting;
P2 = (40*305.372)/288.706 = 42.31 psi
Then, gauge pressure would read 42.31 psi.
