7. Solve y" + y = cos(21) 8. Solve y" + y = cos(t) 9. Solve y-v-y + y = 42 10. Find the Wronskion of the given puit of functions: ele Simplify 11. A mass weighing 2 Ib stretches a spring by 0.5 ft. The spring is displaced 1 ft below the equilibrium and then relensed. The spring is in a medium that exerts a viscous resistance of 6 lb when the mass has a velocity of 3 ft/sec. (Assume g = 32 ft/seca), Formulate the initial value problem. Do not solve
