A parachutist whose mass is 65 kg drops from a helicopter hovering 1500 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 20 N-sec/m when the chute is closed and b2 90 N-sec/m when the chute is open. If the chute does not open until the velocity of the parachutist reaches 25 m/sec, after...

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 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,...

A skydiver weighing 170 lb (including equipment) falls vertically downward from an altitude of 13,000 ft and opens the parachute after 18 s of free fall. Assume that the force of air resistance, which is directed opposite to the velocity, is of magnitude 0.55|?|0.55|v| when the parachute is closed and is of magnitude 18|?|18|v| when the parachute is open, where the velocity ?vis measured in ft/s. Assume that acceleration due to gravity has magnitude 32 ft/s/s; remember that weight is...

With solutions please.
Thanks.
1)A base-jumper jumps off a stationary balloon at 6000 ft, free-falls for 6 seconds at which point the parachute opens. After the chute opens, he decelerates to 18 ft/s in 3 seconds, and then drifts downwards at constant velocity to impact. Find maximum speed during this event. Hint: Break problem into three parts -free fall through deceleration after chute opening, and constant velocity b. Find total time. air where the object is accelerating downwards, motion. 2...

On planet Tehar, the free-fall acceleration is the same as that on Earth, but there is also a strong downward electric field that is uniform close to the planet's surface. A 2.36-kg ball having a charge of 5.02 μC is thrown upward at a speed of 20.1 m/s. It hits the ground after an interval of 4.10 s. What is the potential difference between the starting point and the top point of the trajectory? (Use 9.8 m/s2 for the acceleration...

6. [10 points) For the following question, to model the free fall of a falling rock, assume the usual idealizing simplifications for solving "free fall" problems. Work with the approximate value g = 9.8 m/s2 for the Earth's gravitational acceleration. Consider the following experiment. The Leaning Tower of Pisa is known worldwide for its nearly four- degree lean. The height of the tower is 55.86 meters from the ground on the low side, and 56.67 meters on the high side....
