Skydiver jumps from and airplane, calculate relative velocity and acceleration of the airplane as observed by the skydiver.
At a certain instant after jumping from airplane A, skydiver B is in the position shown and has reached a terminal (constant) speed vg = 50 m/s. The airplane has the same constant speed VA = 50 m/s, and after a period of level flight is just beginning to follow the circular path shown by radius ρ = 2000 m. (a) Determine the velocity and acceleration of the airplane relative to the skydiver. (b) Determine the time rate of change of the speed u, of the airplane and the radius of curvature p, of its path, both as observed by the nonrotating skydiver.

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...

The airplane, traveling at a constant speed of 60 m/s. is executing a horizontal turn. If the plane is banked at θ=20°, when the pilot experiences only a normal force on the seat of the plane, determine the radius of curvature ρ of the turn. Also, what is the normal force of the seat on the m pilot if he has a mass of 75 kg 3)

Relative Velocity and Projectile Motion . a)An airplane moves horizontally with a constant velocity VA/G 300m/s with respect to ground at height H = 600m. The plane fires a container, which has a speed VC/A = 300m/s and direction α = 300 with respect to the airplane immediately after the firing. The container performs a projectile motion and hits the ground at a horizontal distance L from the point of the firing (see figure a)What is the velocity (horizontal and...

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...
