Question
A vessel at rest explodes into three pieces. Two pieces having equal mass fly off perpendicular to one another with the same velocity 30 meter per second. The third piece has three times mass of each of other piece. The magnitude and direction of the velocity of the third piece will be
Options
A.10 √2 m/second and 135o from either
B.10 √2 m/second and 45o from either
C.
m/second and 135o from either
m/second and 135o from eitherD. m/second and 45o from either
m/second and 45o from eitherSolution
Using momentum conservation
P3 =
3mV3 =
3mV3 = 30m √2
V3 = 10√2 m/s
