A transverse wave pulse, described by

is initiated at t = 0 in a stretched string.

a. Write an equation describing the displacement y(x, t) of the traveling pulse as a function of time t and position x if it moves with a speed of 2.5 m/s in the negative x-direction.

---

b. Plot the pulse at t = 0, t = 2 s, and t = 5 s.
