An object with total mass mtotal = 15 kg is sitting at rest when it explodes into three pieces. One piece with mass m1 = 4.8 kg moves up and to the left at an angle of 0, = 24° above the -x axis with a speed of v, = 28.3 m/s. A second piece with mass m2 = 5.2 kg moves down and to the right an angle of 02 = 29° to the right of the -y axis at a speed of v2 = 21.5 m/s.
