1. The problem statement, all variables and given/known data A bicycle is turned upside down while its owner repairs a flat tire. A friend spins the other wheel of radius 0.4 m and observes that drops of water fly off tangentially. She mea- sures the height reached by drops moving ver- tically. A drop that breaks loose from the tire on one turn rises 36.3 cm above the tangent point. A drop that breaks loose on the next turn rises 31.6 cm above the tangent point (the angular speed of the wheel is decreas- ing). Find the angular deceleration of the wheel. The acceleration of gravity is 9.8 m/s2 . As- sume the angular deceleration is constant. Answer in units of rad/s2. 2. Relevant equations Max height = (Vi^2)/2g 2pi(r) Angular Velocity 3. The attempt at a solution Given what I know I converted units 36.3 cm to .363m 31.6 cm to .316m Then used max height formula to determine the Vi Vi1 = 2.6674 m/s Vi2 = 2.4887 m/s and with this I can find the time buy using the circumference and the velocities to determine the times. T1= .9422s for one complete cycle T2= 1.0099s for one complete cycle And with this I need to use angular acceleration formula to get this, but here is where I am lost and fell like I am going in wrong direction. Can I get some guidance into what I should do next. I know that I might have to use this to find tangent line which between these two to find acceleration...in this cause deceleration. But I am lost.
