Determine the displacement and distance covered by a man if he walks 10 m north, turns east and walks 20 m, and then turns right and walks 10 m.

The graph below represents the work done by a student while running up flights of stairs. determine the student's power output after 10 seconds: 1600 j/s 8000 j/s 160 j/s 800 j/s

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.

Does current flow through or across a resistor?
