"Barrel of Fun" Carnival Ride, and the relationship between Friction and ω Homework Statement A ”Barrel of Fun” consists of a large vertical cylinder that spins about its axis fast enough so that any person inside will be held against the wall. Assume: At an angular speed ω1, an upward...

My class hasn't covered themodynamics, or sound yet, but I don't want everyone thinking I'm secretly trying to get a homework answer! So here's my attempt... I'll be researching as I go so don't hold it against me! I might need some help at various stages in my problem. =) 1) G/U: V=8oz...

I've always chuckled when I look up in my classroom and see the poster my physics teacher owns asking "How long would you have to yell to heat up a cup of coffe?". It would take an impracticle amount of time for a single person, however, with a twist this question could turn into quite the...

Oh wait >.< My bad, I typed up the wrong title for my question. Yes, your right haha, the distance traveled would be represented by x. Sorry, its late. But you did help me indirectly =P

Oh your saying the second cosθ=1 because the angle between the force and displacement is 0°! So that would give me: Work = (μ)(mgcosθ)*x*1 Now That seems more reasonable haha!

Homework Statement A box of mass m with an initial velocity of v0 slides down a plane, inclined at θ with respect to the horizontal. The coefficient of kinetic friction is μ. The box stops after sliding a distance x. How much work is done by friction? Homework Equations...
