A skydiver jumps out of an airplane at a high altitude and
reaches terminal speed.
Which of the following statements about the falling skydiver at
terminal speed is FALSE?
The air resistance force does negative work on the skydiver.
The gravitational force on the skydiver must be larger than the air
resistance force in order to maintain a downward velocity.
At terminal speed, the kinetic energy of the skydiver is
constant.
The thermal energy of the skydiver-Earth-atmosphere system is
increasing.
The gravitational potential energy of the skydiver-Earth-atmosphere
system is decreasing.
Homework Answers
reaching terminal velocity indicates that the gravitational force is just in balance with resistance due to atmosphere,
so option 2 is false, hence it is the correct answer

A 50kg skydiver jumps out of an airplane. We assume that the forces acting on the body are the force of gravity and a retarding force of air resistance with direction opposite to the direction of motion and with magnitude cv^2 where c=.1275 kg/m and is the velocity of the skydiver at time t (and upward is positive velocity). The gravitational constant is 9.8 m/s^2 . a) Find a differential equation for the velocity. b) Determine the terminal velocity in...
When an object falls in Earth's gravitational field (think of a skydiver jumping from an airplane or a marble falling in a tank of oil)
When an object falls in Earth's gravitational field (think of a skydiver jumping from an airplane or a marble falling in a tank of oil), it accelerates due to the force of gravity. If gravity were the only force acting on the object, then all objects-elephants and feathers alike would fall at the same rate. But gravity is not the only force present. Moving objects also experience resistance or friction from the surrounding medium; it would be air resistance for...

A skydiver jumps off of an airplane. The plane flies at an altitude of 4 km, and at a speed of 100 km/hr. The skydiver "jumps" by simply letting go of the plane and falling out. Gravity is the only thing affecting their motion until they open their parachute at a height of 2.5 km. After opening their parachute, they experience constant acceleration until they land perfectly, with...

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 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...

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?
