A fighter plane at sea is landing upon an aircraft carrier deck. When the aircraft lands, it must 'catch' a restraining elastic line in order to come to a halt. If the 12,000 kg aircraft has a landing speed of 70 meters/sec and must be brought to a halt in 120 meters, what is the magnitude of the K for the restraining line?

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
