An object with total mass mtotal = 16.8 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 01 = 22° above the -x axis with a speed of v1 = 27.6 m/s. A second piece with mass m2 = 5.3 kg moves down and to the right an angle of 02 = 27' to the right of the -y axis at a speed of v2 = 22.5 m/s.

An object with total mass mtotal = 16.8 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 01 =
22° above the -x axis with a speed of v1 = 27.6 m/s. A second piece with mass m2 = 5.3
kg moves down and to the right an angle of 02 = 27° to the right of the -y axis at a
speed of v2 = 22.5 m/s.
