- In a pendulum, is it angular velocity or angular acceleration that is proportional to sin (theta)?Two pendula are shown in the figure. Each consists of a solid ball with uniform density and has a mass M. They are each suspended from the ceiling with massless rod as shown in the figure. The ball on the left pendulum is very small. The ball of the right pendulum has radius 1/2 L.Randomized Variables L = 1.3 m a) Find the period T of the left pendulum for small displacements in s. b) Find the period T of the right pendulum for small displacements in s.The end of a nanoscale cantilever used for weighing DNA molecules oscillates at 8.8 MHz with an amplitude of 5.0 nm. What are (a) the maximum speed and (b) the maximum acceleration of the end of the cantilever?
- Orangutans can move by brachiation, swinging like a pendulum beneath successive handholds. If an orangutan has arms that are 0.90 m long and repeatedly swings to a 20° angle, taking one swing immediately after another, estimate how fast it is moving in m/s.An air-track glider attached to a spring oscillates between the 20 cm mark and the 70 cm mark on the track. The glider completes 15 oscillations in 30 seconds. Calculate the period, frequency, angular frequency, and amplitude.Question: A conical pendulum is constructed with a string length of 0.475 meters and is set into motion with a radius of 0.180 meters. What is the period of the pendulum's circular motion? My Comments: I'm using F = m* (v^2 / r) and I am solving for velocity which comes out to approximately 1.33 m/s. Is that what they are looking for and is period the same thing as velocity since it is moving in circular motion? Also, why is the string length given? Am I supposed to be using that information or is it to throw me off? Just curious if I'm missing out on what I need to know.
