A large boulder is at rest, and Ben puts a stick of dynamite in the middle of it. The explosion fires 3 chunks of rocks along the ground at different angles. One piece receives a force of 500 N [N], another receives a force of q N [S 45 E], and the last one receives a force of 850N [N r W]. Solve for q and r.
