A(n) 8.0-kg object is sliding across the ice at 2.34 m/s in the positive x direction. An internal explosion occurs, splitting the object into two equal chunks and adding 19J of kinetic energy to system. The explosive separation takes place over a 0.16-s time interval. Assume that the one of the chunks after explosion moves in the positive x direction. The x component of the average acceleration of this chunk during the explosion is afront x, the x component f_o the average acceleration of the other chunk during the explosion is a rear x. What are the x components of the average accelerations of the two chunks during the explosion?
