A body of mass \( 2 \, \text{kg} \) begins to move under the influence of time dependent force \( \\vec{F} = (2 \, \\hat{i} \, t + 6 \, t^2 \, \\hat{j}) \, \text{N} \), where \( \\hat{i} \) and \( \\hat{j} \) are unit vectors along x and y-axis respectively. The power produced by the force at \( t = 2 \, \text{s} \) is _______ \( \text{W} \).
