A small electric motor turns at 1500 revolutions/min. Express the angular velocity, in radians per second, in exact form.

3)The earth has a radius of approximately 6400 km. How many radians per second is the earth rotating at the equator? What is the speed of the earth, in kilometres per hour? If the earth rotates 2°, how many kilometres has it rotated at the origin?
