Calculate the kinetic and potential energies at points $A$ and $B$.
Substitute the given values:
The velocity vector is $\mathbfv = \fracd\mathbfrdt = (4t + 3) \mathbfi + (2t - 2) \mathbfj + 3 \mathbfk$. At $t = 2$ s, $\mathbfv = 11\mathbfi + 2\mathbfj + 3\mathbfk$. Calculate the kinetic and potential energies at points
