The second angle of a triangular kite is three times as large as the first. the third angle is 20 degrees more than the sum of the other two angles. find the measure of each angle. 1st angle: 2nd angle: 3rd angle:

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).
