A30 kg body is moving through space in the positive direction of an x axis with a speed of 170 m/s when, due to an internal explosion, it breaks into three parts. one part, with a mass of 6.1 kg, moves away from the point of explosion with a speed of 69 m/s in the positive y direction. a second part, with a mass of 11 kg, moves in the negative x direction with a speed of 580 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.
