1. there is a speck of dust on the second hand, Where is the speck located if its velocity is: (a) the fastest it could be (b) the slowest it could be

2. In rad/s, what is the angular velocity of the second hand?

A merry-go-round makes 2 complete rotations in 9.6 s. What is its angular velocity?

Is this average or instantaneous? Explain.

A car increases speed from 2pi/3 rad/s to 3pi/2 rad/s in 5.0 s. What is the angular acceleration of the car?

Thanks for the help(Worried)
