This is a question on momentum.
By law of conservation of linear momentum:
Initial momentum = Final momentum
Momentum = mass × velocity
Initial momentum:
For the person = 0 × 6 = 0
Let v be the velocity of the particle and m the mass of the particle.
Its momentum = mv
Final momentum
The final speed = 1/3 × 6 = 2
Final momentum = (m + 6)2
= 2m + 12
Equating the two
2m + 12 = vm
Vm - 2m = 12
M (v - 2) = 12
m = 12/(v - 2) kg
