QAIPM-2001-Ph-2940: NEET 2001 Physics - Class 11 AIPM-2001-Ph-2940 Solution: A 1 kg stationary bomb is exploded in three parts having mass…
A 1 kg stationary bomb is exploded in three parts having mass 1:1:3 respectively. Parts having same mass move in perpendicular direction with velocity 30 m/s, then the velocity of bigger part will be
Multiple Choice Options
- A m/sec
- B m/sec
- C m/sec
- D m/sec
Step-by-Step Verified Solution
Apply conservation of linear momentum.
Total momentum before explosion
= total momentum after explosion
0 = m 5 v 1 i ^ + m 5 v 2 j ^ + 3 m 5 v _ 3
3 m 5 v _ 3 = _ m 5 [ v 1 i ^ + v 2 j ^ ]
v _ 3 = _ v 1 3 i ^ _ v 2 3 j ^
_ v 1 = v 2 = 30 m/sec
v _ 3 = _ 10 i ^ _ 10 j ^ ; v 3 = 10 2 m/sec
