A parachutist including parachute has a mass, m = 90 kg.
At the moment when the parachute opens, the hopper falls vertically
at a speed of 41.0 m / s.
With open parachute, the amount of air resistance (in Newton) is:
5.2 * v ^ 2.
(Question) How large is the amount of the "final speed", ie when the fall distance becomes infinitely long?

A parachutist including parachute has a mass, m = 90 kg. At the moment when the parachute opens, the hopper falls vertically at a speed of 41.0 m / s. With open parachute, the amount of air resistance (in Newton) is: 5.2 * v ^ 2. (Question) What is the amount of the jumper's speed when the jumper has fallen 10.1 m from the point where the parachute opened?

A parachutist bails out and freely falls 54 m. Then the parachute opens, and thereafter she decelerates at 2.6 m/s2. She reaches the ground with a speed of 3.1 m/s. (a) How long is the parachutist in the air? (b) At what height does the fall begin?

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...

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.

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 15 kg mass is suspended 15 m above the floor when the cable suspending it snaps. Ignore air resistance and friction. Find Mechanical Energy (E) of the system. It falls half the distance to the floor. Find Kinetic Energy (K). At this point, what would the mass's speed be? What would the masses speed be just before hitting the floor?

A skydiver jumps off of an airplane. The plane flies at an altitude of 4 km, and at a speed of 100 km/hr. The skydiver "jumps" by simply letting go of the plane and falling out. Gravity is the only thing affecting their motion until they open their parachute at a height of 2.5 km. After opening their parachute, they experience constant acceleration until they land perfectly, with...
