These are questions related to causes of friction!
Help is appreciated ^.^
If we repeat the slide of the plastic but wet the table first, what will happen? More friction or less?
If we spray a little oil on the wet table and repeat the sliding experiment, what will happen?
What would happen if you tried to slide a rubber eraser across the table? Why?

Asilver dollar is dropped from the top of a building that is 1324 feet tall. use the position function below for free-falling objects. s(t) = −16t2 + v0t + s0 (a) determine the position and velocity functions for the coin. s(t) = v(t) = (b) determine the average velocity on the interval [1, 2]. ft/s (c) find the instantaneous velocities when t = 1 second and t = 2 seconds. v(1) = ft/s v(2) = ft/s (d) find the time required for the coin to reach the ground level. (round your answer to three decimal places.) t = s (e) find the velocity of the coin at impact. (round your answer to three decimal places.) ft/s
