Thank you! I seriously thought I was crazy for a moment in thinking this after HallsofIvy said "All that is important is one rose and the other fell the same distance." To me that sounds like the hieghts they each rise and fall are the same. On to the next thing, am I using the correct...
I think watermelonpig is saying Impulse= Force(average) x Time Interval. I=Ft. I think most physics books call change in momentum, impulse, so maybe that will help. Your also given the time...
I'll try to explain what I mean to the people who tell me that m1 and m2 move up and down the same height.
Imagine an extremely long incline plane, with a very small degree angle, like 15-25 degrees. Two masses are connected by an extremely long, rope that doesn't not stretch. m1's bottom is...
Ok, but it does matter whether or not they start from the same height, at least how I view it. Because work done is CHANGE in Gravtational potential energy (Ugf-Ugi) for both m1 and m2 (system). You can only have one GPE reference point where U=0, and if they are initially at different...
So what your saying is, the distance m1 moves up the slope is the same as the height m2 fell.
Ok, but we still arn't given that they both start at the same height... If we work out the math, having our potential energy reference at the bottom of the incline (h below m2).
W(g)=ΔUg...
Homework Statement
System is initially at rest, if m2 falls a distance h. What is the work done by gravity on the system.
Given: Theta, m1, m2, h
The image looks fairly similar to this.
Homework Equations
I'm going to go ahead and assume we are using Work(gravity)=The change in...
