.
(a)  the angular speed of the carousel in radians per minute = 


      = 4 revolutions per minute =   radians per minute = 4*2*3.14 radians per minute =  


      = 25.12 radians per minute.     ANSWER




(b)  The linear speed (in feet per minute) of the platform rim of the carousel = 

     = the angular speed multiplied by the radius = 25.12 radians per minute multiplied by (50/2) feet = 


     = 25.12*25 = 628 feet per minute.    ANSWER


Answered, solved and completed.
