How many cm/s2 of acceleration should correspond to 1 unit of ramp slope if:a graph of number of paper clips needed to maintain equilibrium vs. ramp slope has slope 84 clips / unit of ramp slope, and
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 ( 12 cm/s2) / clip?
If we require 75 clips 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?
84 clips/unit of ramp slope * 12 cm/s^2 / clip
= 1008 cm/s^2/unit
m = 75 clips
F = m * a
= 75 clips * 12 cm/s^2
= 900 clips-cm/s^2
a = F/m
= (900 clips-cm/s^2) / 84 clips
= 10.7 cm/s^2

These questions are not worded well. Your answers are good.
