In a mechanics experiment, a student picks up four different discs with different radii and sets them in uniform circular motion. For each disk, the tangential speed of a point near the outside edge is recorded. The recorded values for are inconsistent.
Disk Speed Radius Acceleration
1 57 cm/s 20 cm 163 cm/s2
2 40 cm/s 10 cm 190 cm/s2
3 95 cm/s 40 cm 226 cm/s2
4 70 cm/s 30 cm 163 cm/s2
