A 3-kg bomb initially at rest explodes into three equal mass pieces. One mass moves to the left (negative x-direction) at 60 m/s and another mass moves down (negative y-direction) at 80 m/s.
(a) What is the speed and direction (with respect to the positive x-axis) of the third mass?
(b) How much kinetic energy was released in the explosion?
