A movie stunt woman drops from a helicopter that is 27.0 m above the ground and is moving with a constant velocity whose components are 12.0 m/s upward and 18.0 ms/ horizontally and toward the south. where on the ground (relative to the position of the helicopter when she drops) should the stunt woman have placed the foam mat to break her fall?

A helicopter 9.00 m above the ground and descending at 2.90 m/s drops a package from rest (relative to the helicopter). We have chosen the positive positive direction to be upward. The package falls freely. Just as it hits the ground, find the y-component of the velocity of the package relative to the helicopter. Just as it hits the ground, find the y-component of the velocity of the helicopter relative to the package.
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 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 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 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,...
