An aircraft is coming in for a landing at 300 meters height when the propeller falls off. the aircraft is flying at 40.0 m/s horizontally. the propeller has a rotation rate of 20 rev/s, a moment of inertia of 70.0kg-m2 , and a mass of 200 kg. neglect air resistance. (a) with what translational velocity does the propeller hit the ground? (b) what is the rotation rate of the propeller at impact?

As a car drives with its tires rolling freely without any slippage, the type of friction acting between the tires and the road is 100) a) static friction. b) kinetic friction. c) a combination of static and kinetic friction. d) neither static nor kinetic friction, but some other type of friction. e) it is impossible to tell what type of friction acts in this situation.

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.
