Dominique places0.5 kgin the bucket and9.5 kgin the cart and allows the setup to oscillate with an amplitude of2 cm. As the paper moves horizontally with constant speedvpast the oscillating pencil, the pencil draws the graph shown. Each square on the graph represents1 cm. Recall that the pencil pointed to the highest line of the grid when neither the bucket nor the cart carried any mass, and everything was at rest. Calculate the speedvthat the paper was moving and include units in your answer. Explain each part of your calculation with words. Now suppose there was a small amount of friction between the pencil and paper, enough to affect the vertical motion of the bucket but not cause the bucket to swing back and forth horizontally. How, if at all, would this affect the calculated speed?
