A mosquito lands on a phonograph record
5.0 cm from the record’s center. If the record turns clockwise so
that the mosquito travels along an arc length of 5.0 cm, what is the mosquito’s
angular displacement?

A bicyclist rides along a circular track.
If she travels around exactly half the track in 10.0 s, what is her average
angular speed?

A remote-controlled car’s wheel accelerates
at 22.4 rad/s2. If the wheel begins with an angular speed of 10.8
rad/s, what is the wheel’s angular speed after exactly three full turns?
