You walk into an elevator, step onto a scale, and push the "up" button. You recall that your normal weight is 621 N .

When the elevator has an upward acceleration of magnitude 2.70 m/s2 , what does the scale read? (792 N)

If you hold a 3.81-kg package by a light vertical string, what will be the tension in this string when the elevator accelerates as in the previous part?

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...

When you reach Point Park, it's time to take the elevator up to class Let's say someone left a big spring on the floor of the elevator, and you have to step on it to fit in and let the doors close. The elevator accelerates upward at 3.0 m/s2. The spring constant is 2.5 Times 10^3 N/m. By how much is the spring compressed? You can use your own mass for this problem, or if you prefer, say it's around...
