Calculations and Concepts Using Freebody Diagrams A type of elevator called a cage is used to raise and lower miners in a mine shaft. Suppose the
cage carries a group of miners down the shaft. If the unbalanced force on the cage is 60.0 N, and
the mass of the loaded cage is 1.5 x 102kg, what is the acceleration on the cage?
Miners do not like using the cage, so they walk down stairs to enter the mine
O 0.400 m/s^2
4.0 m/s^2
1.5 x 10^2 kg

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.

The uniform slender bar rests on a smooth horizon- tal surface when a force f is applied normal to the bar at point a. point a is observed to have an initial acceleration aa of 20 m/s2, and the bar has a corre- sponding angular acceleration of 18 rad /s2. deter- mine the distance b.
