Your weight is 120 lb. Suppose you are standing on a scale in an elevator moving up with a constant speed of 4 m/s. What would be the reading on the scale?

If air resistance can be ignored, which of the following graphs will be a straight line for a falling object?

NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.Refer to the graph of distance versus time. The speed of the object is largest

A body is suspended from a spring hanging vertically. The body is then pulled downward so the spring stretches. Consider the change in the elastic potential energy (EPE) of the spring and the change in gravitational potential energy (GPE) as the body is pulled down.

High-quality care is always 1. safe. 2. efficient. 3. inexpensive. 4. physician administered.

A ball is thrown straight up. It reaches its highest point and then falls back. Which of the following is the correct statement?

Which of the three curves show the speed of an object that is beginning to experience significant air resistance?

A car is decelerating at the rate of 2 km/s2. If its initial speed is 66 km/s, how long will it take the car to come to a complete stop?

Two velocity vectors are added: one of magnitude 2.0 m/s and one of magnitude 5.0 m/s. Not knowing the respective directions, we can say that the magnitude of the sum of the vectors will be
