How far is the pendulum from the wall when it is farthest away? How far is the pendulum from the wall when it is closest? What is the amplitude of the sinusoidal function? How did you determine this? Does it start at a max, min, or middle point? What is the period of the function? How did you determine this?

A spring-mass system shown in the diagram below is free to oscillate in the vertical direction. I+s unstretched x0 motion The position (x) of the spring is positive when the spring is below the equilibrium position. If the block is displaced from its equilibrium position by a distance x, show that its equation of motion is given by: K m Why is it that the equation of motion does not include the force of gravity? In which direction does the velocity of the moving mass have a positive value?

An object of mass 0.30 kg hanging from a spring is lifted 2.5 cm above its equilibrium position and is dropped from rest. What is the amplitude of the subsequent oscillation? Explained your reasoning.

In the simple pendulum experiment, a student gets 5 oscillations in 10 second and the length of the simple pendulum is 1 m. What is the gravity acceleration? and what length do we make the rod pendulum so that it has the same frequency as the simple pendulum?
