APFIVE Conservation Of Momentum In An Explosion
A 0.50 kg firecracker at rest explodes into three fragments. Two fragments of mass 0.10 kg each travel perpendicular to each other with speeds of 30 m/s and 40 m/s, respectively. What is the velocity (magnitude and direction with respect to the 30 m/s fragment) of the third fragment, which has mass 0.30 kg?
A
35 m/s at 143° from the 30 m/s fragment
B
25 m/s at 135° from the 30 m/s fragment
C
16.7 m/s at 233° from the 30 m/s fragment
D
50 m/s at 143° from the 30 m/s fragment
