A 21 kg body is moving through space in the positive direction of an x axis with a speed of 190 m/s when, due to an internal explosion, it breaks into three parts. One part, with a mass of 6.8 kg, moves away from the point of explosion with a speed of 71 m/s in the positive y direction. A second part, with a mass of 7.2 kg, moves in the negative x direction with a speed of 480 m/s. What are the (a) x-component and (b) y-component of the velocity of the third part? (c) How much energy is released in the explosion? Ignore effects due to the gravitational force.
