Problem

Two waves passing through a region are represented by

y_1 = (1.0 \text{ cm}) \sin [(3.14 \text{ cm}^{-1}) x - (157 \text{ s}^{-1}) t]

and

y_2 = (1.5 \text{ cm}) \sin [(1.57 \text{ cm}^{-1}) x - (314 \text{ s}^{-1}) t]

Find the displacement of the particle at

x = 4.5 \text{ cm}

at time

t = 5.0 \text{ ms}
