In the pervious question (6), the magnitude of the momentum transferred during the hit is

Answer»

ZERO
`0.75 kg -MS^(-1)`
`1.5 kg ms^(-1)`
`14 kg ms^(-1)`

Solution :(b) By previous solution `Deltap=-(0.9hati+1.2hatj)`
Magnitude =`|Deltap|=sqrt((0.9)^(2)+(1.2)^(2))`
`=sqrt(0.81+1.44)=1.5 kg ms^(-1)`
