Question
A bicycle is turned upside down while its owner repairs a flat tire. A friend spins the other wheel and observes that drops of water fly off tangentially. She measures the heights reached by drops moving vertically (see figure below). A drop that breaks loose from the tire
on one turn rises vertically 58.0 cm above the tangent point. A drop that breaks loose on the next turn rises 42.0 cm above the tangent point. The radius of the wheel is 0.335 m.
