1. A pendulum is constructed on Laurus using a mass of 4 kg and a wire of length 0.71 m. Find the oscillation frequency of this pendulum (in Hz).

2. While shopping at a grocery store on Laurus, you place a 0.2 kg eggplant on a spring scale, which causes it to stretch 5 cm. You then pull the scale down an additional 4 cm and release it, causing the scale to oscillate up and down. How long (in seconds) would it take the eggplant to move from its lowest point to its highest point?

3. If the eggplant is released from rest at a position of x = +4 cm at time t = 0, what is the position of the eggplant (in cm) at t = 1.2 s?
