APFIVE Two-Dimensional Momentum Conservation In An Explosion
A 2.0 kg object moving at 6.0 m/s undergoes an explosion, splitting into two fragments. One 0.5 kg fragment moves perpendicular to the original direction at 8.0 m/s. What is the velocity (magnitude and direction) of the second fragment relative to the original direction?
A
12 m/s along the original direction
B
6.0 m/s at 45° from the original direction
C
10 m/s at 14° from the original direction
D
8.2 m/s at 21° from the original direction
