Quiz 3

1.  It feels like time is standing still as you’re watching your favorite coffee mug slide towards the edge of your frictionless kitchen table. You’ve realized there’s no chance to stop it, so you decide to do the next most logical thing: Quickly calculate where on the floor it will meet its demise and see how close you are!

You estimate that the table’s surface is 1.00 m above the ground and that the mug is moving horizontally with a speed of 1.07 m/s when it reaches the end of the table. How far from a point on the floor directly beneath the table’s edge will the mug land?

Give your answer in centimeters rounded to a reasonable number of significant figures.

2.   In no more than 100 words, describe the logic you used to arrive at your answer to the previous question. Please do not write out a step-by-step mathematical solution—instead, explain the logic used to arrive at your answer. For example, you might want to address some or all of:

• What assumptions did you make?
• What physical relationships did you need to know?
• Which quantities were known and unknown?
• Was there a key equation (or two) that you used to find that unknown?
