Sorry to ask Rahul, but are you on the revleft and rebelalliance forums by any chance? We do have a certain rahul from India...

Great! Thanks, these forums are going to be useful for this year. Just wanted to make sure I have some other things right. So, speed = distance/time, the amount of distance covered in a certain amount of time Velocity = Final displacement from starting point/time, shows how much you...

That was my orginal answer, 0/40...so, the average velocity is zero...? That was easier than I thought! :rolleyes:

Zero, that is her final displacement.

So, then, her total displacement being 5km? So 5km divided by 40 min giving me .125km as the velocity?

New to physics, and I'm a little confused on one problem on my homework: 1) A runner runs 5.0km along the course east, then turns around and runs 5.0km west along the same path. She returns to the starting point in 40 min. What is her average speed and velocity? The speed was easy to...
