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 his landing on a hard floor? Draw a free-body diagram to aid your calculations.

John jumps out of an airplane at a height of 10,000 feet and opens his parachute. He quickly reaches a terminal velocity of 53 m/s. When he is 146 m above a hovering supply helicopter (and 500 m above ground), a supply package is dropped. The package is small enough that the air resistance is negligible. Will John reach the package? If not, how close does he come?

003 10.0 points A man jumps from an airplane and does not open his parachute immediately. As he falls, two forces act on him: the force mg due to gravity and the force na of air resistance. Now he opens his parachute and begins to fall at constant velocity What forces act upon him now? 1. Since he is falling at constant velocity the force of air resistance no longer acts on him. 2. The same two forces act on...

Assuming all of the rom overcoming air resistance (ignoring internal resistances and stopping/starting much would we need to reduce the 70 mph speed limits vehicle emissions are how to obtain a 20 percent cut in greenhouse er emissions from cars? 14.

1. A rocket is launched vertically from the Earth, and the thrust (pushing force) from the engines is directed upward, and has a magnitude of 5.00 x 106 N. The mass of the rocket is initially 2.00 x 105 kg. (a) What is the initial acceleration of the rocket, assuming you can neglect air resistance? (b) After the rocket has been in flight for a while, burning and exhausting a lot of fuel, its mass has decreased to 1.20 x 105 kg, and...

fast was Stan going at the time of impact?
Stan the Man, from the local circus, was a human cannon ball. While practicing one day, he was shot out of a cannon and into a canyon and subsequently died. It is believed it was murder but suicide cannot be ruled out, yet. Here are the facts of the case One afternoon, Stan climbed into the cannon for reasons we do not know. According to...
