A skydiver jumps from a plane and deploys her parachute. Do not neglect air resistance. After the parachute is deployed, will the sum of kinetic energy plus potential energy be conserved (K+P=constant)? Why/why not?
Homework Answers
Since there is considerable air resistance so energy will dissipate due to air resistance hence sum of KE + PE can't be constant Therefore sum of kinetic energy + Potential energy will decrease with time and can't be conserved.

Suppose a skydiver jumps out of a plane at 15,000 meters above the ground. It takes him 2.0 seconds to pull the cord to deploy the parachute and another 2.0 seconds for the parachute to be fully deployed. Additionally, in order to land safely on the ground, his parachute must be fully deployed 10.0 seconds before he hits the ground. With this information and assuming there is no additional air resistance or changes in atmospheric density, what is the maximum...

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....

After deploying her parachute, a skydiver falls through the air with a constant speed of 9.00 m/s. As she falls, there is a constant breeze blowing west at 4.00 m/s.

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...

Translate the following real-world scenario into signals. Write mathematically. A parachute jumper with mass 80 kg rides in a plane at 4000 m above sea level (ASL). At an arbitrary time zero, the jumper jumps out of the plane. At a height of 750 m, she deploys her parachute, after which she keeps a constant vertical velocity of 8m/s. Ignoring air resistance for the portion of her drop before parachute deployment, write an analytical expression of her height as a...

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...
