Which of the following correctly describes the motion of a real object in free fall? Assume that the object experiences drag force proportional to speed and that it strikes the ground before reaching terminal speed. It will fall with increasing speed and

The diagram represents two skydivers, an instructor (70 kg) and a student (60kg),connected by a harness. While descending they measure their acceleration to be 2 ?/?2 while they experience air drag, ? drag (it is mostly due to the aerodynamic profile of the student, who takes the “front seat”).Calculate this ? drag force.

An elevator loaded with tourists has a mass of 1750 kg. a.) The elevator accelerates upward (in the positive direction) from rest at a rate of 1.55 m/s2 for 2.3 s. Calculate the tension in the cable supporting the elevator in newtons b.) The elevator continues upward at constant velocity for 8.5 s. What is the tension in the cable, in Newtons, during this time? c.) The elevator experiences a negative acceleration at a rate of 0.65 m/s2 for 2.6 s. What is the tension in the cable, in Newtons, during this period of negative accleration? d.) How far, in meters, has the elevator moved above its original starting point?

A 60 kg person stands on a bathroom scale in an elevator. What does the scale read if the person is accelerating upward at 1.5 m/s²? +588 N O 678N 498 N ΟΟΝ

A skydiver of mass 83.5 kg jumps from a slow-moving aircraft and reaches a terminal speed of 54.4 m/s. (a) What is her acceleration when her speed is 30.0 m/s? magnitude  m/s2 direction  ---Direction--- upward downward (b) What is the drag force on the skydiver when her speed is 54.4 m/s? magnitude  N direction  ---Direction--- upward downward (c) What is the drag force on the skydiver when her speed is 30.0 m/s? magnitude  N direction  ---Direction--- upward downward
