Solved in 3 steps
- hat number w.ww The word "units" refers to the corresponding quantity of something. For example, 2 is a number; 2 seconds is a physical quantity that has the units of second. In physics problems, are usually not looking for a number; we are looking for a need to also know the units. If you do not include units with the answer, you will not receive physical quantity, which means we full credit. Physicists are very nitpicky about this! 8. You may have learned the formula distance speed x time. How long would it take in seconds to travel a distance of 2000 meters if you are traveling at a speed of 25 meters per second?
