Work Power And Energy

A body of mass 1kg begins to move under the action of a time dependent force \(\overrightarrow F = \left( {t\widehat i + 3{t^2}\,\widehat j} \right)\) N, where \(\widehat i\) and \(\widehat j\) are the unit vectors along \(x\) and \(y\) axis. The power developed by above force, at the time t = 2s, will be ____________ W.
