A skydiver weighing 170 lb (including equipment) falls vertically downward from an altitude of 13,000 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|?|0.55|v| when the parachute is closed and is of magnitude 18|?|18|v| when the parachute is open, where the velocity ?vis measured in ft/s. Assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is...

With solutions please.
Thanks.
1)A base-jumper jumps off a stationary balloon at 6000 ft, free-falls for 6 seconds at which point the parachute opens. After the chute opens, he decelerates to 18 ft/s in 3 seconds, and then drifts downwards at constant velocity to impact. Find maximum speed during this event. Hint: Break problem into three parts -free fall through deceleration after chute opening, and constant velocity b. Find total time. air where the object is accelerating downwards, motion. 2...

CAN YALL PLEASE HELP ME I HAVE 4 HOURS TO DO THESE!! THANK YOU!! Question 1 A mass of 4 kilograms of air in a piston-cylinder assembly undergoes two processes in series from an initial state where p1 = 0.3 MPa, T1 = 211°C: Process 1–2: Constant-temperature expansion until the volume is twice the initial volume. Process 2–3: Constant-volume heating until the pressure is again 0.3 MPa. Assuming ideal gas behavior, determine the temperature at state 3, in kelvin. _________________________________________________...
