Taylor runs in lane one around a curve, while Morgan runs in lane eight around a curve. The radius of lane eight is twice as big as the radius of lane one. If Taylor has to run 50 m to get fully around the curve in lane one, how many meters does Morgan have to run to get fully around the curve in lane eight?

4. Two cars travel around a circular track, one on an inner lane of radius 12.0 m, and one on an outer lane of radius 16.0 m. The cars initially have the same speed of 15.0 m/s. (a) What are the centripetal accelerations of the two cars initially? (b) What speed would the car in the outer lane need so that it would complete one full loop in the same time as the car in the inner lane? (c) If...

The figure shows three rotating, uniform disks that are coupled by belts. One belt runs around the rims of disks A and C. Another belt runs around a central hub on disk A and the rim of disk B. The belts move smoothly without slippage on the rims and hub. Disk A has radius R; its hub has radius 0.471R; disk B has radius 0.244R; and disk C has radius 2.02R. Disks B and C have the same density (mass...

Strings are wound around two pucks identical in size. One string is around the pucks outer rim, while the other is around a smaller axle in the middle, as shown. A radius of the outer rim is twice that of an axle. A side view of the pucks is also included for clarity. You start pulling the pucks with the same force F at the same time, and the pucks are originally at rest. They slide on a frictionless surface....
