Line q and line m are cut by transversal lines j& k the lines and the measures of some of the angles created by the intersections of the lines are shown in the diagram below. what is the measure of angle 4?

Amass weighing 16 pounds stretches a spring 8/3 feet. the mass is initially released from rest from a point 2 feet below the equilibrium position, and the subsequent motion takes place in a medium that offers a damping force that is numerically equal to 1/2 the instantaneous velocity. find the equation of motion if the mass is driven by an external force equal to f(t)=cos(2t).
