You (mass = 75 kg) are riding in an elevator while standing on a scale. As the elevator begins to rise, you notice that the scale reading briefly increases to 785 N. What is the acceleration of the elevator during this time? Assuming it has three times the acceleration as it slows to rest at the top floor, what does the scale read as it slows?

(13.1) An elevator riding in a frictionless vertical shaft has total mass of 1000 kg. (a) The elevator cable exerts a force of 9000 N in the upward direction on the elevator. Determine (i) the acceleration of the elevator, and (ii) how long it takes for the elevator, starting from rest, to attain a speed of 5 m/s. (b) The cable exerts a force of 12000 N [up] on the elevator. Determine (i) the acceleration of the elevator, and (ii)...

A 75-kg person stands on a weight scale in an elevator and pushes the button to go up. The elevator accelerates upward at 3 m/s2, then rises at a steady speed of 15 m/s, and finally decelerates at the top floor at a rate of 2 m/s2. Match the force values to their descriptions. Some values may be used more than once, and some may not be used at all. 1. person's weight during upward acceleration 2. scale reading during...
