You are conducting an experiment inside an elevator that can move in a vertical shaft. a load is hung vertically from the ceiling on a string. the tension in the string is measured to be exactly equal to the force due to gravity on the load. no other forces are acting on the load. which of the following statements about the elevator are correct? check all that apply. check all that apply. the elevator is an inertial frame of reference. the elevator is not an inertial frame of reference. the elevator may be at rest. the elevator may be moving at a constant velocity upward. the elevator may be moving at a constant velocity downward. the elevator may be accelerating. the elevator must be accelerating.

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)
