A parachutist whose mass is 60 kg drops from a helicopter hovering 1000 m above the ground and falls toward the ground under the influence of gravity. Assume that the force due to air resistance is proportional to the velocity of the parachutist, with the proportionality constant b 30 N-sec/m when the chute is closed and b2 100 N-sec/m when the chute is open. If the chute does not open until the velocity of the parachutist reaches 15 m/sec, after...

A parachutist whose mass is 75kg drops from a helicopter hovering 2000 m above the ground and falls toward the ground under the influence of gravity. Assume that the force due to air resistance is proportionality constant b1=30 N-sec/m when the chute is closed and b2=90 N-sec/m when the chute open. If the chute does not open until the velocity of the parachutist reaches 20 m/sec, after how many seconds will she reach the ground use g=9.81

A parachutist whose mass is 80 kg drops from a helicopter hovering 2500 m above the ground and falls toward the ground under the influence of grevity. Assume that the force due to air resistance is proportional to the velocity of the parachutist, with the proportonality constant b,-30 N secim when the chute is closed and b2 100 N sec/m when the chute is open. If the chute does not open until the velocity of the parachutist reaches 20 m/sec,...

An object of mass 700 kg is released from rest 1000 m above the ground and allowed to fall under the influence of gravity. Assuming the force due to air resistance is proportional to the velocity of the object with proportionality constant b=50 N-sec/m, determine the equation of motion of the object. When will the object strike the ground? (Hint: Here the exponential term is too large to ignore. Use Newton's method to approximate the time t when the object...

(1 point) Math 216 Homework webHW3, Problem 6 A person leaps from an airplane 6000 feet above the ground and deploys her/his parachute after 9 seconds. Assume that the air resistance both before and after deployment of the parachute results in a deceleration proportional to the person's velocity, but with a different constant of proportionality. Before deployment, take the constant to be 0.11, and after deployment use the value 1.6. (The acceleration due to gravity is 32.2ft/sec2. Note also that...

According to a newspaper account, a paratrooper survived a training jump from 1214 ft when his parachute failed to open but provided some resistance by flapping in the wind. Allegedly he hit the ground at 97.5 mih after falling for 7 seconds. To test the accuracy of this account, you should first find the drag coefficient p, assuming a terminal velocity of 97.5 mi/h and also that the resistance of the paratrooper falling through the air is proportional to his...
