question 30

Multiple Choice

If two bicyclists move around a circular track of radius 100 m, at the same speed, 10 m/s, but in opposite directions, then

• A) one has centripetal acceleration of 1 m/s² and the other has centrifugal acceleration of 1 m/s².
• B) they have opposite accelerations, +1 m/s² (inward) and -1 m/s² (outward).
• C) they have equal size accelerations, 1 m/s².
• D) they might have different accelerations, depending on whether they have identical mass or not.
