Homework Statement
If the slope of a graph of the acceleration of a cart vs. the number of paper clips attached by a string and suspended over a pulley is ( 20 cm/s2) / clip, and if the slope of a graph of number of paper clips needed to maintain equilibrium vs. ramp slope is 47 clips / unit of ramp slope, then how many cm/s2 of acceleration should correspond to 1 unit of ramp slope? If 52 clips are necessary to match the mass of the cart, then if we could apply this force to the cart without the extra mass of all those clips, what would be the acceleration of the cart?
Homework Equations
I was thinking of using maybe one of the constant acceleration equations.
v = v0 + a t
x = x0 + v 0 t + 1/2 a t ^ 2
v ^ 2 = v 0 ^ 2 + 2 a ( x - x 0 )
avg v = ( v+ v 0 ) / 2
v = velocity
v 0 = initial velocity
a = acceleration
t = time ( seconds )
x0 = initial position
x = position
The Attempt at a Solution
I am completely confused with this question. I have put in over 10 hours, and tried to find out help all over the internet. I am looking for a lot more than just the answer, because I want to learn this stuff. If someone could walk me through this I would greatly appreciate it.
