Angular speed for the 2nd hand on a clock is blank radians per second. Estimate your answer using pi=3.14 and round to the nearest 100th

Answer 1

To find angular speed, we need to know the number of radians traveled in a certain time (in this case time in seconds). There are 2π radians in one complete revolution of a circle and the 2nd hand of a clock makes 1 complete revolution (2π radians) in 60 seconds. So the angular speed is 2π/60 radians/sec = (2)(3.14)/(60) = 0.10 radians/sec
