4. An object, initially travelling at 45 m/s [N], explodes into three pieces. Afterward, the first piece has a mass of 6kg, and travels at 68 m/s [N25E]. The second piece has a mass of 2.5kg, and obtains a new velocity of 26 m/s [N75W]. a) If the third piece has a mass of 4kg, determine its vector velocity after the explosion. b) Determine the change in energy.
