A4 kg body is traveling at 3 m/s with no external force acting on it. at a certain instant an internal explosion occurs, splitting the body into two chunks of 2 kg mass each. the explosion gives the chunks an additional 18 j of kinetic energy. neither chunk leaves the line of original motion. determine the speed and direction of motion of each of the chunks after the explosion.

This problem has been solved! see the answera non-uniform fire escape ladder is 6.0m long whenextended to the icy alley below. it is held at the top by africtionless pivot, and there is neglibible frictional force fromthe icy surface at the bottom. the ladder weighs 250n, and it'scenter of gravity is 2.0m along the ladder from the bottom. amother and child of total weight 750n are on the ladder 1.5m fromthe pivot. the ladder makes an angle θ with the horizontal.find the magnitude and direction ofa) the force exerted by the icy alley on the ladderb) the force exerted by the ladder on the pivotc) do your answers in part a and b depend on the angle?
