... o If you drive 4 mi at 30 mph and then 4 mi at 50 mph, is your average speed greater than, equal to, or less than 40 mph? Since it takes 8 minutes to travel 4 mi at 30 mph and 4.8 minutes to travel 4 mi at 50 mph, it takes 12.8 minutes to travel 8 mi and therefore, the speed is 37.5 mph, which is le ...

... 6. After pushing against a brick wall for a long time, you are feeling extremely tired, but you have not done any work on the wall. Explain. In order for work to be done the force needs to cause the displacement. If there is no displacement no work is done. 7. By what factor does the kinetic energy ...
