Did you get 103.5 J?

Ok, thank you so much. I undertand.

Homework Statement A 4.2 kg object, initially at rest, "explodes" into 3 objects of equal mass. Two of these are determined to have velocities of equal magnitudes (5.0 m/s) with directions that differ by 90 degrees. How much kinetic energy was released in the explosion? (that is what is the...

Oh, ok I get it. It is impulse divided by time.

Ok, you completely lost me, but I think I figured it out. This certain graph increases, remains constant, then decreases. Do I take the final force of each section, add it to the initial force of each section, divide that value by the time of that section, then average those together?

This is really simple, but I can not remember how to find the average force in a Force vs TIme graph.
