Homework Statement
An 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 16 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 a(front,x), the x component of 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?
Homework Equations
V[cm] = (m[1]v[1]+m[2]v[2]) / (m[1]+m[2]) = v[1] for this problem since there is only one initially moving mass
K[e,cm] = 1/2 * m[total] * v^2[cm]
probably more equations but I'm not sure
The Attempt at a Solution
I honestly don't even know where to begin with this problem. I'm really lost in this class so far and I don't understand how to work in the 16 joules or how kinetic energy changes in a center of mass reference frame. Please help
