How do I solve this ?

Question

Adam ant sits on the second hand of a clock, 12 cm from the center. What is his angular velocity in revolutions per minute ?

Answer 1

Angular velocity ω = 1rev/min, because second hend perform 1 full revolution in 1 minute;

Answer: ω = 1rpm

Answer 2

Think about the second hand. It returns to the top of the clock once every minute Thus, its angular velocity in revolutions per minute is 1. (In revolutions per minute, since the minute hand returns to the top once each hour, its angular velocity would be 1 revolution/hour * 1 hour/60 minutes = 1/60 revolution per minute.)
