Homework Answers
when the body was falling initially without opening parachute two force were acting, one gravitational force and other is friction force due to air resistance...... but when he open the parachute then force due to air resistance increase because force due to air resistance is directly proportional to velocity and area of body..... when velocity increases then a state comes where air friction is equal to force due to gravity, so acceleration of body is zero, means constan velocity is achieved.
so option 3 will be best possible answer amoung the all other options.

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?

An airplane pilot fell 340 m after jumping from an aircraft without his parachute opening. He landed in a snowbank, creating a crater 1.30 m deep, but survived with only minor injuries. a) Assuming the pilot's mass was 94.0 kg and his terminal velocity was 45.0 m/s , estimate the work done by the snow in bringing him to rest. Model him as a particle. b) Estimate the average force exerted on him by the snow to stop him. c)...

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...

1. If a sky-diver jumps out of a plane, two forces will act on him, gravity and air resistance. If we assume air resistance is proportional to the velocity, we get the total force on the sky diver will be F = −gm − kv, where g is a acceleration due to gravity on the surface of the earth, m is the mass of the sky-diver, v is the velocity of the sky-diver, and k is constant of proportionality 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,...

According to a newspaper account, a paratrooper survived a training jump from 1214 ft when his parachute failed to open but provided some resistance by flapping in the wind. Allegedly he hit the ground at 97.5 mih after falling for 7 seconds. To test the accuracy of this account, you should first find the drag coefficient p, assuming a terminal velocity of 97.5 mi/h and also that the resistance of the paratrooper falling through the air is proportional to his...
