    String with masses on either end being pulled from the center

    Homework Statement Two equal 1 kg masses are connected by a light 1.6 m string on a flat frictionless surface. A 2 N force is applied to the midpoint of the string which causes the system to accelerate in the positive x-direction. After 1.5 seconds, the rope makes an angle of 55° with the...
