Problem

A particle has velocity v=2 ı^+3 ȷ^−1 k^ m s−1\mathbf v = 2\,\hat\imath + 3\,\hat\jmath - 1\,\hat k\,\text{m\,s}^{-1} and is acted upon by a force F=4 ı^−1 ȷ^+2 k^ N\mathbf F = 4\,\hat\imath - 1\,\hat\jmath + 2\,\hat k\,\text{N}. Determine the instantaneous power transferred to the particle.
