APFIVE Conservation of Momentum in an Explosion
An object of mass 3.0 kg, initially at rest, explodes into three fragments. One 1.0 kg fragment moves at 5.0 m/s along the positive x-axis, and another 1.0 kg fragment moves at 3.0 m/s along the positive y-axis. Determine the speed and direction of the third fragment, where the direction is the angle measured from the positive x-axis.
A
4.0 m/s at 270° from the positive x-axis
B
2.7 m/s at 233° from the positive x-axis
C
5.8 m/s at 211° from the positive x-axis
D
8.0 m/s at 53° from the positive x-axis
