b. In a local bar, a customer slides an empty beer mug on the counter for a refill. The bartender does not see the mug, which slides off the counter and strikes the floor 1.40m from the base of the counter. If the height of the counter is 0.860m, (a) with what speed did the mug leave the counter and (b) what was the direction of the mug's velocity just before it hit the floor?

A turtle crawls along a straight line, which we’llcall the x-axis with the positive direction to the right. The equationfor the turtle’s position as a function of time is x 1t2 = 50.0 cm +(2.00 cm/s)t - (0.0625 cm/s2)t2. At what times t is the turtle a distance of10.0 cm from its starting point? What is the velocity (magnitude and direction)of the turtle at each of those times?
