Question

The minute hand of a bedside clock is 2.5 cm long. In order for the clock to keep proper
time, the minute hand should maintain an average angular velocity of
bobpursley
IT makes one round (2PI radians) per hour,

speed= 2PIrad/hr*1hr/3600sec*2.5cm or
speed= 0.00436332313 cm/second
They ask for an angular velocity. That would be independent of the minute hand's length, and would be (2*pi rad/h)/(3600 sec/h) = 1.745*10^-3 rad/s
