The vertical portion of string was cut after 4 seconds X = $84 Find the new acceleration a2 of the 25-kg object Find the distance d2 moved by the 25-kg after 3 seconds with the new acceleration a2. Find the kinetic energy of the (3.5 - X/30) kg object at 3 seconds after the string was cut. Find the total loss of potential energy of the 25-kg after moving d1 and d2 meters
