    please clarify when you can and please use easy to read hand writting. always upvote, thanks! Assume that while ascending, an elevator has the same magnitude of acceleration "a" during starting (accelerating) and stopping (decelerating). A person stands on a scale in that elevator, and hence pushes downwards on the scale. The scale also reacts with an upward normal force. The maximum and minimum scale readings are Nace = 600 N and N dec = 400 N, respectively. acceleration of...

    A 68-kg man stands on a spring scale in an elevator. Starting from rest, the elevator ascends, attaining its maximum speed of 1.2 m/s in 0.77 s. The elevator travels with this constant speed for 5.0 s, undergoes a uniform negative acceleration for 1.8 s, and then comes to rest. (a) What does the spring scale register before the elevator starts to move? N (b) What does the spring scale register during the first 0.77 s of the elevator's ascent?...

    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...
