In this problem, are launching a projectile. The projectile covers a horizontal distance of 1.40m. The projectile also loses height, Δy = -1.22. Since the projectile is moving horizontally on the table, this is a horizontal launch problem.
Uniform accelerated motion (UAM) equations, a.k.a. "kinematics equations":
In a local bar a customer slides an empty beer mug down the counter for a refill. The height of the counter is 1.22 m. The mug slides off the counter and strikes the floor 1.40 m from the base of the counter.
(a) With what velocity did the mug leave the counter?
(b) What was the direction of the mug's velocity just before it hit the floor?
