(17-78) Cylinders A (10 lb) and B (5 lb) are connected by a massless cord over a 3-lb pulley (a uniform disk). If the system is released from rest, find the speed of the cylinders 0.5 s later. The cord does not slip on the pulley. What would the speed be if the pulley were massless

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.
