Momentum and CollisionHard
Question
A canon shell moving along a straight line bursts into two parts. One part moves with momentum 20 N-s making an angle 30o with original line of motion. The minimum momentum other part of shell can have is.
Options
A.0 N-s
B.5 N-s
C.10 N-s
D.Depends on mass of individual particles.
Solution
For the minimum value of momentum of other part it must be directed in negative Y-direction.
Momentum is conserved along both x & y direction for the minimum value of P′.
Pynet = 0 ⇒ P′ - 20 cos 60o = 0 ⇒ P′ = 10 N-s
