A carousel with a 50foot diameter makes 4 revolutions per minute.
a) Find the angular speed of the carousel in radians per minute.
b) Find the linear speed in feet per minute of the platform rim of the carousel.

angular speed is frequency * 2pi = 8pi rad/min
linear speed = angular speed * radius = 8pi * 25 = 200pi ft/min
