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?Slope=20cm/s/s/clip

47/unit

20cm/s/s*47clips=

940cm/s/s/unit

1040cm/s/s

I am not 100% sure I understood what the question was asking so I answered as to what thought.

There's really only one way to interpret the question, and whether you completely understood the context or not, you did interpret it correctly.
