Ok Thanks. My professor didn't give us that equation so I'm not sure if we can use it.

Just want to see if I did everything right. I'm notorious for simple mistakes. Homework Statement A 100kg man concerned about his weight decides to weigh himself in an elevator. He stand on a bathroom scale in an elevator that is moving upward at 3.0 m/s. As the elevator reaches his floor, it...

Gehh sorry. Why do I keep forgetting that? a. How far does the bike skid? b. What was the elapsed time before the bike stops skidding?

Homework Statement a 100kg bicycle and rider initially move at 16 m/s up a 15 degree hill. The rider slams on the brakes and skids to rest. The coefficient of friction is (0.8, 0.7) Homework Equations I have a few but nothing to do with a coefficient of friction. The last ones given to...

Opps I did leave out a little. It was late when I wrote this. It should say "From this light, a separate cable suspends a second 0.80 kg light. The elevator is moving downward at 4.0 m/s (where I got v1) when someone presses the emergency stop button."

That is it. There is no real question given other then blanks for the values of t1, t2, r1, r2, v1, v2 and a12. I have given everything I was given to solve the problem

Homework Statement A decorative light fixture in an elevator consists of a 2.0 kg light suspended by a cable from the ceiling of the elevator. From this light, a separate presses the emergency stop button. During the stop, the upper cable snaps. The elevator engineer says that the cable could...

Thanks. I think I have a handle on things now. Youtube helped some as well.

Trying to do my first Physics home work assignment for college and I'm not really making any headway. He went thru the martial so fast while throwing in calculus that I'm not sure if I do or don't need. My main problem with Motion Diagrams is I'm not sure how accurate I'm supposed to be and...
