document.write( "(a)  the angular speed of the carousel in radians per minute = \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "      = 4 revolutions per minute =   radians per minute = 4*2*3.14 radians per minute =  \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "      = 25.12 radians per minute.     ANSWER\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "(b)  The linear speed (in feet per minute) of the platform rim of the carousel = \r\n" );
document.write( "\r\n" );
document.write( "     = the angular speed multiplied by the radius = 25.12 radians per minute multiplied by (50/2) feet = \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "     = 25.12*25 = 628 feet per minute.    ANSWER\r\n" );
