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...

2. A 60 kilogram skydiver (more correctly termed a "skyflopper", as the picture below indicates) jumps from a plane at a height of 1000 meters with an initial velocity of v(0) = 0 meters per second, and falls subject to air resistance whose magnitude is given by 15e, for 25 seconds. At this time his parachute opens and the air resistance is now 180. Assume that the positive direction is downward and the gravitational acceleration constant is g -9.8 m/s,...

A man jumps out from an aeroplane. As the man falls, he opens his parachute. What is the man’s terminal velocity if his drag coefficient with his parachute is 0.55, the combined mass of the man-parachute system is 80 kg, the surface area of the man and his parachute is 10 m^2 , and air density is 1.225 kg/m^3 . If a human can survive up to 13 m/s impact speed on a hard floor, can the parachuting man survive...

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...

James Bond leaps without a parachute from a burning airplane flying at 15,000 ft. Seconds later, his assistant, who was following behind in another plane, dives after him wearing her parachute and clinging to one for her hero. Is it possible for her to catch up with Bond and save him? Yes, because whereas Bond has no parachute, his assistant has two and will have a higher mass. Yes, because Bond can orient himself horizontally and spread his limbs to...
