The speed at which a grandfather clock runs is controlled by a swinging pendulum. a) If you find that the clock loses time each day, what adjustment would you need to make to the pendulum so it will keep better time? b). If the pendulum currently is 15 cm, by how much would you need to change the length to make the period lesson by 0.04 s? Use scientific notation rounding to the nearest hundredth.

A 50-cm-long spring is suspended from the ceiling. A 250 g mass is connected to the end and held at rest with the spring unstretched. The mass is released and falls, stretching the spring by 20 cm before coming to rest at its lowest point. It then continues to oscillate vertically. a. What is the spring constant?b. What is the amplitude of the oscillation? c. What is the frequency of the oscillation?
In the past, the fact that a simple pendulum has a constant period has been used as the basic timing mechanism for clocks. As a matter of fact, an old "Grandfather Clock" did use the swing of its pendulum to generate the ticks of the clock. Suppose you wanted a pendulum to have a period of 2.50 seconds, how long would it have to be (calculate to 3 significant digits).
