A 10,000-lb airplane is launched from a catapult. The spring of the catapult (ks = 150 lb/in) is initially compressed 10 ft and then released. During the launching, the airplane engine exerts a constant horizontal force of 2,000 lbs. Assuming the friction to be negligible, determine the takeoff speed of the airplane at the instant when the spring reaches its undeformed position. wwwww k,= 150 lb/in.
