In a local bar, a customer slides an empty beer mug down the counter for a refill. The height of the counter is 1.30 m. The mug slides off the counter and strikes the floor 1.20 m from the base of the counter.
(a) With what velocity did the mug leave the counter?
m/s
(b) What was the direction of the mug's velocity just before it hit the floor?
° (below the horizontal)
