A 11 kg body is moving through space in the positive direction of an x axis with a speed of 310 m/s when, due to an internal explosion, breaks into three parts. One part, with a mass of 6.4 kg, moves away from the point of explosion with a speed of 58 m/s in the positivey direction. A second part, witha mass of 1.9 kg, moves in the negative x direction with a speed of 630 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.

Question
A 11 kg body is moving through space in the positive direction of an x axis with a speed of 310 m/s when, due to an internal explosion, it
breaks into three parts. One part, with a mass of 6.4 kg, moves away from the point of explosion with a speed of 58 m/s in the positive y
direction. A second part, witha mass of 1.9 kg, moves in the negative x direction with a speed of 630 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.
