1. Consider the free-body diagram: or * V is constant 2. We can see that ∅= Tcos mg because the weight is not moving up or down. = +- = Fy TS on W Ww 0 3. Tsin is equal to the centripetal force. 4. ∅= Tsin centripetal force 5. The centripetal force is based off the . Wcent and mass m .

Unformatted text preview: marker every rotation. 21. Finding v experimentally 1. Measure C by adding k and R . 2. Find the circumference using ( + ) 2π k R 3. Upon spinning the system, keep the weight over the slide marker to maintain a constant ∅ and constant v . 4. Record the amount of time it takes to make a full rotation at a constant v . Take the time elapsed 22. 23.times of revolutions, Average time = 2.53s, Velocity = d/t = 1.43/2.53 = .565m/s 24.2.39 25.2.41 26.2.37 27. 2.39 28.2.43 29.2.41 30.2.52 31. 2.56 32.2.52 33.2.6 34.2.7 35.2.69 36.2.67 37.2.63 38.2.64 39.2.52 40.2.53 41.2.48 42. 43....
