Let E be the solid unit cube with diagonally opposite corners at the origin and (1, 1, 1), and faces parallel to the coordinate planes. Let S be the surface of E, oriented with the outward-pointing normal. Use a CAS to find $\iint_S \mathbf{F} \cdot d\mathbf{S}$ using the divergence theorem if $\mathbf{F}(x, y, z) = 3xy\mathbf{i} + 5ye^x\mathbf{j} + x \sin(z)\mathbf{k}$. (Round your answer to four decimal places.)

4) A 1.5-kg mass attached to an ideal massless spring with a spring constant of 20.0 N/m oscillates on a horizontal, frictionless track. At time $t = 0.00$ s, the mass is released from rest at $x = 10.0$ cm. (That is, the spring is stretched by 10.0 cm.) (5 points each) a) Find the frequency of the oscillations. b) Determine the maximum speed of the mass. At what point in the motion does the maximum speed occur? c) What is the maximum acceleration of the mass? At what point in the motion does the maximum acceleration occur? d) Determine the total energy of the oscillating system. e) Express the displacement $x$ as a function of time $t$.
