An objects acceleration is given by \(\vec a = \cos \left( {2t} \right)\,\vec i + 4{t^3}\,\vec j + 6\sin \left( {3t} \right)\vec k\). The objects initial velocity is \(\vec v\left( 0 \right) = 6\,\vec i + 2\vec j + 7\vec k\) and the objects initial position is \(\vec r\left( 0 \right) = \vec i - 9\vec j + 6\vec k\). Determine the objects velocity and position functions.
An objects acceleration is given by \(\vec a = 10t\,\vec i - 6\,\vec j + t\cos \left( t \right)\vec k\). The objects initial velocity is \(\vec v\left( 0 \right) = - \,\vec i + 11\vec j - \vec k\) and the objects initial position is \(\vec r\left( 0 \right) = 4\vec i + \vec j + 10\vec k\).
