Multiplechoice questions may continue on the next column or page find all choices before answering. 001 10.0 points Calculate the speed at the edge of a disc of radius 2 . 5 cm that rotates at the rate of 10 rev / s. Answer in units of m / s. 002 10.0 points A girl sitting on a merrygoround moves counterclockwise through an arc length of 3.75 m. If the girls angular displacement is 2.48 rad, how far is she from the center of the merrygoround? Answer in units of m. 003 10.0 points A car tire rotates with an average angular speed of 29 rad/s. In what time interval will the tire rotate 3 . 5 times? Answer in units of s. 004 10.0 points A figure skater begins spinning counterclock wise at an angular speed of 4.1 rad/s. Dur ing a 4.7 s interval, she slowly pulls her arms inward and finally spins at 8.7 rad/s. What is her average angular acceleration during this time interval?
