[4] An unloaded helicopter of mass 10,000 kg hovers at sea level while it is being loaded. In the unloaded hover mode, the blades rotate at 400 rpm. The horizontal blades above the helicopter cause a 18-m-diameter air mass to move downward at an average velocity proportional to the overhead blade rotational velocity (rpm). A load of 14,000...

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 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 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 landing craft with mass 12,500 kg is in a circular orbit 6.75×105 m above the surface of a planet. The period of the orbit is 5200 s. The astronauts in the lander measure the diameter of the planet to be 9.60×10^6m. The lander sets down at the north pole of the planet. What is the weight w of an 85.6 kg astronaut as he steps out onto the planet's surface?

A mountain bicycle with 26 inch (0.660 m) diameter tires (mass of 15 kg, mass of each tire is 1 kg) has a rider (mass of 100 kg). The rider travels along a flat road with a speed of 10.0 m/s. The road then goes uphill with a slope of 1.4 degrees. If the rider is not pedaling and you ignore friction and air drag, how far up the hill does the rider on the bike go?

equipment. A 3.0-m-diameter merry-go-round with a mass of 300 kg is spinning at 15 rpm . John runs tangent to the merry-go-round at 4.8 m/s , in the same direction that it is turning, and jumps onto the outer edge. John's mass is 30 kg. Part A: What is the merry-go-round's angular velocity, in rpm, after John jumps on?
