SUMMARY
The equation y = (2m) cos(kx), with k = 2 m^-1, is dimensionally correct. In this equation, y represents a distance measured in meters (m). The term (2m) indicates a distance, while the argument of the cosine function, kx, must also be dimensionless. Since k has units of m^-1, and x is in meters, the product kx is dimensionless, confirming the equation's dimensional integrity.
