Last Thursday, I went for a walk through my neighborhood. I started at my house. My smart watch told me that I walked a total of 3.5 miles. I started my walk at 5 pm and ended at 8 pm. At the end of my walk, I was 50 meters north of my house visiting a neighbor. I wanted to find my average velocity on the trip. My distance walked was 3.5 miles. My time was 3 hours. To find velocity, I used my calculator to find 3.5 miles divided by 3 hours which equaled 1.16 miles per hour. Did I accurately calculate my velocity? If not, what did I do wrong and what was my correct velocity?

The necleus of an atom is made up of what subatomic particles?

As you are trying to move a heavy box of mass m, you realize that it is too heavy for you to lift by yourself. there is no one around to , so you attach an ideal pulley to the box and a massless rope to the ceiling, which you wrap around the pulley. you pull up on the rope to lift the box. use g for the magnitude of the acceleration due to gravity and neglect friction forces. once you have pulled hard enough to start the box moving upward, what is the magnitude f of the upward force you must apply to the rope to start raising the box with constant velocity? express the magnitude of the force in terms of m, the mass of the box.
