How many cm/s2 of acceleration should correspond to 1 unit of ramp slope if: a graph of the acceleration of a cart vs. the number of paper clips attached by a string and suspended over a pulley has

slope ( 20 cm/s2) / clip, and a graph of number of paper clips needed to maintain equilibrium vs. ramp slope has slope 45

clips / unit of ramp slope?

45 clips/unit slope * 20cm/s/s clip = 900cm/s/s per unit ramp slope

If 43 clips are required 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?

(43clips / 45clips) * 900cm/s/s = 860cm/s/s"

&#Very good work. Let me know if you have questions. &#
