Week 5 Quiz2 Version 1If the slope of a graph of the acceleration of a cart vs. the number of paper clips attache
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?
So if for each clip you accelerate 20cm/s^2 and for each unit there is 47clips/unit... then you would do
47clips*20cm/s^2 = 940cm/s^2 for 1 unit of ramp slope.
52clips *20cm/s^2 = 1040cm/s^2"
Good. Let me know if you have questions.
