1. The problem statement, all variables and given/known data In a local bar, a customer slides an empty beer mug down the counter for a refill. The bartender is momentarily distracted and does not see the mug, which slides off the counter and strikes the floor 0.90 m from the base of the counter. The height of the counter is 0.840 m. 2. Relevant equations r=vot + 1/2(a)t2 Vf=Vo + at Vf2=Vo2+2ar 3. The attempt at a solution Tried finding time for the y component but ended up with square roots of negative numbers and I've been stuck on this for awhile. I have a lot of other problems like this so if I know how to do this one it would really help me out on the rest.
