During a military training in Camp Jizmundo, Libas, Banga, Aklan , a sky diver of weighing 82 kg ( including equipment ) falls vertically downward from an altitude of 1500 meters, and opens the parachute after 10 sec of free fall. Assume that the force of air resistance is proportional to velocity. The air drag coefficient before opening the chute is k, = 1.65 kg/sec , when the parachute is closed and after opening the chute k, = 26.4 kg/sec.Take g = 9.8 m/s. (a) Find the speed of the sky diver when the parachute opens ? (b) Find the distance fallen before the parachute opens. %3D %3D %3D
