In a local bar, a customer slides an empty beer mug down the counter for a refill. The height of the counter is 1.38 m. The mug slides off the counter and strikes the floor 1.00 m from the base of the counter. (a) With what velocity did the mug leave the counter? X Does the time required for the mug to hit the floor depend on its initial horizontal velocity? m/s b) What was the direction of the mug's velocity just before it hit the floor? X How does the x component of the velocity of the mug just before it hits the floor compare to its initial velocity? (below the horizontal)
