Momentum and CollisionHard
Question
A1 kg particle strikes a wall with velocity 1 m/s at an angle 30o and reflects at the same wall in 0.1 second then the force will be :
Options
A.30√3 N
B.0
C.40√3 N
D.10√3 N
Solution
= m [v cos θ -(-v cosθ)]
= 2mv cos θ
2×1× cos 30o = 2×
Rate of change of momentum
This will be equal to force, so force = 10√3 N
