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?

Explain the difference between each pair of concepts. a. frequency and relative frequency b. percentage and relative frequency a. select the correct choice below. a. frequency is the total number of observations in a data set. relative frequency is the number of times a particular distinct value occurs. b. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of a value to the total number of observations. c. frequency is the total number of observations in a data set. relative frequency is the ratio of the number of times a particular distinct value occurs to the frequency. d. frequency is the number of times a particular distinct value occurs. relative frequency is the ratio of the frequency of two different values.
