As a runner crosses the finish line of a race, she starts decelerating from a velocity of 9 m/s at a rate of 2 m/s^2. Take the r
unner's velocity as she crosses the finish line to be in the positive direction. What is the runner’s displacement, in meters, during the first 5 seconds after crossing the finish line? What is her velocity, in meters per second, 5 seconds after crossing the finish line?
If your atom has a charge of +1, it means you have 1 more proton than electrons. This is because protons have a positive charge and electrons have a negative charge. Because you have 23 protons, and a charge of +1, you have 22 electrons.
