Initially when drive starts
Only force on diver is = Mg (since v(0) =0 m/s -Resistance =0)
As he accelerates down and picks up speed
Net Force = Mg - 15 I v I = Mg - 15 gt for 25 seconds
Velocity at time t = V(0) + = 9.8 t- (15/60) ( 9.8 ) t^2/2 = (9.8 x 25) - (9.8/4) ( 25^2/2) =

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...
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....
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...
Note that the answer is not: - 0 m/s^2 - 7.848 m/s^2 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...
