A mass 26.9 (in grams) suspended from a string of length 65 (in cm) forms a simple pendulum. If its amplitude is θ0 (in degrees), during what fraction of its period can the pendulum be found between + θ ° and - θ °? The initial amplitude is small enough that the motion is simple harmonic to a very good approximation. Express your answer in terms of the given variables.

Question 3 The figure shows a conical pendulum, in which the bob (the small object at the lower end of the cord) moves in a horizontal circle at constant speed. (The cord sweeps out a cone as the bob rotates.) The bob has a mass of 0.035 kg, the string has length L = 1.1 m and negligible mass, and the bob follows a circular path of circumference 0.76 m. What are (a) the tension in the string and (b)...

An ideal pendulum with a length of 0.75 m is oscillating such that its 2.0 kg bob has amaximum speed of 2.0 m/s. (a) What is the amplitude of this motion? (b) Suppose the massless string is replaced with a 2.0 kg rod which is also 0.75 m long. Whatamplitude is required to give the bob a maximum speed of 2.0 m/s?
