1. The problem statement, all variables and given/known data What is the angular speed of the tip of the minute hand on a clock, in rad/s? 2. Relevant equations I thought the equations needed would be angular velocity= change of theta/change in time. 3. The attempt at a solution I worked on this one and am sure it has a simple answer. I know that it moves 2pi radians in 3600 seconds. I figured that to be .001745 rad every second. When I put that answer in, it tells me to check it because I may have rounded incorrectly or used the wrong number of sig figs. Did I at least start this problem correctly?
