Question

2) Consider a block that makes a simple harmonic movement. It does 33 complete cycles of
oscillation every second. Its position varies from 2.6m to -2.6m.
a) Calculate the speed of the block as it passes through its equilibrium position (x = 0). Give a
positive value, in international units.
b) Calculate the acceleration of the block when its position is x = 1.5m. Give the answer in
international units.

This, the length of the pendulum is 1.58 m. Now you start with the pendulum at 20.6 degrees with respect to the vertical, but rather than releasing it from rest, you give it a push downward. It swings to the other side, and reaches a maximum angle of 34.3 degrees with respect to the vertical. What must have been the initial speed of the pendulum just after you pushed it? 1.41 m/s 3.71 m/s 1.85 m/s 2.32 m/s

The block is at rest as shown. What is the peiod of the oscillation if the block is pulled down by 10 cm, in seconds? Use g = 10 m/s2. Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.
