A skydiver is at an altitude of 1,525 m. After 11.0 seconds of free fall, he opens his parachute and finds that the air resistance, FD, is given by the formula FD = −bv, where b is a constant and v is the velocity. If b = 100,and the mass of the skydiver is 86.0 kg, first set up differential equations for the velocity and the position, and then find the following. (Assume air resistance is negligible prior to the...
