A skydiver has a mass of 72 kg and a weight of 706 N. He is descending on a parachute and his speed is still increasing at 1.2 m/s2. What is the magnitude and direction of the net force on the skydiver? Explain. What is the magnitude and direction of the force that the parachute harness exerts on the skydiver? Explain.
3) The velocity v(t) of a skydiver falling to the ground is governed by the equation m dv/dt mg-kv, where g is the acceleration due to gravity, and k>0 is the drag constant associated with air resistance a) Find the analytical solution for V(t), assuming v(0) 0 b) Find the limit of v(t) as t goes to infinity. This is known as the terminal velocity. c) Give a graphical analysis of this problem, and re-derive the formula for the terminal...
When an object falls in Earth's gravitational field (think of a skydiver jumping from an airplane or a marble falling in a tank of oil), it accelerates due to the force of gravity. If gravity were the only force acting on the object, then all objects-elephants and feathers alike would fall at the same rate. But gravity is not the only force present. Moving objects also experience resistance or friction from the surrounding medium; it would be air resistance for...

1. An 84.0 kg sprinter starts a race with an acceleration of 1.44 m/s2. If the sprinter accelerates at that rate for 41 m, and then maintains that velocity for the remainder of the 100 m dash, what will be his time (in s) for the race? 2. (a) If the rocket sled shown in the figure below starts with only one rocket burning, what is the magnitude of its acceleration (in m/s2)? Assume that the mass of the system is 2090...
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...
