A dog is lying in a boat at rest on a calm lake. The dog suddenly wakes up, startled, and leaps in the air. As a result the boat starts bobbing up and down with a vertical position y given by y(t) = 0. 30m · sin(t/t0), t0 = 0. 4s. (a) What kind of motion does this represent? Discuss briefly the possible limitations of this description. (b) What is the amplitude, angular frequency and period of the bobbing motion? (c) Find
