A traditional small, wall-hanging pendulum clock keeps time by having a period of exactly 1.00 seconds. What is the length of the pendulum of such a clock? Show your work.
A small ball is attached to a thread that has a negligible mass and is hung from a support. When the ball is pulled back a small distance and released, it swings in simple harmonic motion with a period of 4.0 s. The ball is replaced with one having 9.0 times the mass. What is the period of the pendulum? Please show your work.

- Show your work please.arrow_forwardChris jumps off a bridge with a bungee cord (a heavy stretchable cord) tied around his ankle, as shown in the figure below. He falls for 15 m before the bungee cord begins to stretch. Chris’s mass is 75 kg. If we neglect air resistance and Chris drops another 43 m before coming to a stop, find the spring constant ? of the bungee cord. Ignore the mass of the cord and treat Chris as a particle. please show your work, including diagrams, algebraic equations, and enough written explanations that somebody who is not familiar with the problem could understand what you are doing.arrow_forwardThe initial swing of a pendulum has an arc length of 30 inches.

- A small ball is attached to a thread that has a negligible mass and is hung from a support. When the ball is pulled back a small distance and released, it swings in simple harmonic motion with a period of 4.0 s. What is the period of the pendulum after the length of the thread is increased by a factor of 9.0? The ball is released the same way each time, and the thread does not stretch. Please show your work.arrow_forwardIf you make a spring stiffer does the angular frequency of oscillation, increase, decrease, or stays the same.
