Question

8. QIC A bicycle is turned upside I--- 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 mov- ing vertically (Fig. P7.8). A drop that breaks loose from the tire on one turn rises vertically 54.0 cm above the tangent point. A drop that breaks loose on the next turn rises 51.0 cm above the tangent Figure P7.8 Problems 8 and 69. point. The radius of the wheel is 0.381 m. (a) Why does the first drop rise higher than the second drop? (b) Neglecting air friction and using only the observed heights and the radius of the wheel, find the wheel's angular acceleration (assuming it to be constant). the arc (a) Det directie 16.

Answer 1

First drop will go higher than the second because the angular velocity is decreasing as well as linear velocity is also decreasing. so it is going less height.
