Assignment:
Question 1. A raft is bobbing up and down in a lake. Its vertical position x above the flat surface of the water is given by x=0.60sin(3.0t+4.2), where distances are in metres and time t is in seconds.
1. What is the boat’s position at t=0? At t=2.8s?
2. What is the period of the raft’s oscillation?
3. What is the boat’s maximum speed during this oscillation?
