A bicycle is turned upsidedown while its owner repairs a flat tire. A friend spins the otherwheel of radius 0.4 m and observes that drops of water fly off tangentially.She measures the height reached by drops moving vertically. A dropthat breaks loose from the tire on one turn rises54.4 cm abovethe tangent point. A drop that breaks loose on the next turn rises51 cm above the tangent point (the angular speed of the wheel isdecreasing).
Find the angular deceleration of the wheel. The acceleration of gravity is9.8m/s2 . Assume the angular deceleration isconstant.
