A(n) 7.7-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 17 j 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 afrontx, the x component fo the average acceleration of the other chunk during the explosion is arearx.
what are the x-components of the average accelerations of the two chunks during the explosion?
