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 1.10 m from the base of the counter. The height of the counter is 0.820 m.

(a) With what velocity did the mug leave the counter?

correct check mark m/s

(b) What was the direction of the mug's velocity just before it hit the floor?

wrong check mark

Your answer differs from the correct answer by 10% to 100%.° (below the horizontal)

2. Relevant equations

I found (a) which is 2.68 m/s

3. The attempt at a solution

For b) i used sqrt(2.68^2+2.68^) = 3.79 and did,

theta = cos^-1(2.68/3.79) which is 45 degrees, which is wrong but since it say below the horizontal axis, will it be -315 degree?
