When does a yo-yo not travel the farthest from the finger?
A.) when the amplitude of the finger moving up and down is greater than the amplitude of the yo-yo
B.) when the amplitude of the finger moving up and down is less than the amplitude of the yo-yo
C.) when the frequency of the finger moving up and down is equal to the resonant frequency of the yo-yo
D.) when the frequency of the finger moving up and down is different from the resonant frequency of the yo-yo

This question has multiple parts
Question 8 Two waves with identical frequency f and amplitude A are superimposed on each other. The waves are partially out of phase (one is shifted by 1/4 wavelength compared to the other). The resultant wave will have: Select the correct answer O Frequency less than f, amplitude equal to 2A O Amplitude exacly equal to 0 O Frequency equal to f,amplitude less than 2A O Frequency equal to f, amplitude equal to 2A Frequency...

Tim attaches the string of a 0.10 kg yo-yo to his finger and releases the yo-yo from rest. As the yo-yo spins down, Tim keeps his finger motionless which allows the yo-yo to be treated the same as a freely rolling object. After the yo-yo drops a distance of 0.90 m, it has a translational speed of 4.0 m/s and an angular speed of 180 rad/s. What is the moment of inertia of the yo-yo? Air resistance and friction are...

8. Two cars, P and Q, travel in the same direction on a long, straight section of a highway. Car P passes car Q, and is adjacent to car Q at time to a. Suppose that car P and car Q each move with constant speed. At time t, is the magnitude of the instantaneous velocity of car P greater than, less than, or equal to the magnitude of the instantaneous velocity of car Q? Explain. Suppose instead that car...
