5. (6 pts) Stan jumps out of an airplane with a parachute. After 34 seconds, he opens the parachute. The graph to the right shows Stan's vertical velocity versus time, in a coordinate system where down is positive.

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...
With solutions please. Thanks. 1)A base-jumper jumps off a stationary balloon at 6000 ft, free-falls for 6 seconds at which point the parachute opens. After the chute opens, he decelerates to 18 ft/s in 3 seconds, and then drifts downwards at constant velocity to impact. Find maximum speed during this event. Hint: Break problem into three parts -free fall through deceleration after chute opening, and constant velocity b. Find total time. air where the object is accelerating downwards, motion. 2...
3. A 180-Ib person jumps out of an airplane with initial upward velocity of 5 ft/s at a height of 3000 ft (assuming the air resistance is proportional to its falling speed). The air resists the body's motion with a force of 2 lb for each ft/s of speed. Assuming the constant gravity is 32 ft/s2. 1. find its velocity v = v(t) 2. find its terminal velocity 3. find the distance of falling x = x(t) 4. find the...
