Question: a skydiver weighing 210 lb including equipment falls vertically downward...

Question details

A skydiver, weighing 210 lb including equipment falls vertically downward from an altitude of 5000 ft and opens the parachute after 10 s of free fall Assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.75 v when the parachute is closed and is o magnitude 10 v when the parachute is open, where the velo y v s measured in S A computer algebra system is recommended. Use g 32 ts2 or the acceleration due to gravi y Round your answers to two decimal places. (a) Find the speed of the skydiver when the parachute opens. 190.71 (b) Find the distance fallen before the parachute opens 131.32 (c) What is the limiting velocity VL after the parachute opens? V-21 (d) Determine how long the sky diver is in the air after the parachute opens. 184 24
