Solve the all parts of following problem:
Problem: In a local bar, a customer slides an empty beer mug down the counter for a refill. The height of the counter is 1.46 m. The mug slides off the counter and strikes the floor 0.80 m from the base of the counter.
Part A: With what velocity did the mug leave the counter?
Part B: What was the direction of the mug's velocity just before it hit the floor?
I need help to determine the direction of the mug's velocity just before it hit the floor.
