The moon orbits the earth at a distance of 3.85 x 10^8 m. assume that this distance is between the centers of the earth and the moon and that the mass of the earth is 5.98 x 10^24 kg. find the period for the moon's motion around the earth. express the answer in days and compare it to the length of a month.

Awind turbine is rotating counterclockwise at 0.5 rev/s and slows to a stop in 10 s. its blades are 20 m in length. (a) what is the angular acceleration of the turbine? (b) what is the centripetal acceleration of the tip of the blades at t=0s? (c) what is the magnitude and direction of the total linear acceleration of the tip of the blades at t=0s?

In which of these cases are the two wave points considered to be in phase with each other?
