# Question: at time t 0 a wave pulse is described...

###### Question details

At time t = 0, a wave pulse is described by the function
y=(9.0/(5.0+x2))

with x and y in cm. The wave pulse is moving in the positive x-
direction with a speed of 3.0 cm/s. At time t = 0.3 s and location
x = 2.0 cm, the displacement, y, is:
