I have an at home lab. That tells me to run up a flight of stairs. My flight of stairs is 3 m (vertical height). To walk up the stairs it takes me 6.98 seconds. To run up the stairs it takes me 2.88 seconds. I need to find the work that is being done. I weigh 118 pounds that is 526 N. How do I come about this I know work is W=(F)(D) So do I need to put my time in seconds into something. But what? Please help me!!
