A mass 20 (in grams) suspended from a string of length 94 (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.
HINTS: Use θ(t) = θ0 sin(ω t) to find ωt, given θ(t) and
θ0.
Note that ω can be expressed in terms of the period of the
motion.
How many times in one cycle does the pendulum swing through the
range between θ ° and - θ °?

A pendulum consists of a uniform rod of total mass m and length L that can pivot freely around one of its ends. The moment of inertia of such a rod around the pivot point is 1/3mL^2 The torque around the pivot point of the pendulum due to gravity is 1/2mgLsinθ, where θ is the angle the rod makes with the vertical and g is the acceleration due to gravity. a) Write down the equation of motion for the angle...

Swing away: a) A pendulum undergoing simple harmonic motion completes a cycle in a time T. If the pendulum’s amplitude is doubled, the time required for one cycle is still T, even though the pendulum covers twice the distance. How can this be? Explain. b) A pendulum is made from a bowling ball sized hollow plastic sphere filled with sand. It is anchored from the ceiling using a 10-ft long rope and set into motion. As it swings, sand leaks...

There is a string L= 11 cm fixed at a turn while a 4-kg molecule
swinging from it. The framework experiences simple harmonic motion.
At t = 0 the molecule is situated at a point θ = 13° relative the
harmony and has zero speed, so the movement of the molecule is
depicted as θ(t)=θmax⋅cos(ωt).

A mass M attached to a string of length L forms a simple pendulum. The coordinate system is chosen such that the motion to the right is the positive direction. At t=0, the mass is traveling to the right through equilibrium, with amplitude of oscillation A. Write down the symbolic sinusodial time dependence for position x(t). Your answer should only be in terms of: A, g, L and t. Include minus signs and trigonometric functions as needed. A.) x(t)=? x(t)=-Asin(wt)=Asin((sqrt(g)/L)*t)...
