In the previous problem (3), the magnitude of the momentum transferred during the hit is

Answer»

<P>zero
0.75 KG `-ms^(-1)`
1.5 kg `-ms^(-1)`
14 kg `-ms^(-1)`

Solution :`1.5 kg- m s^(-1)`
As provedin ABOVESOLUTION
`Delta p =-[ 0.9 HAT(j )+ 1.2 hat(j )]`
Magnitude=`|Delta p |= sqrt ((0.9)^(2) + (1.2)^(2))`
`= 1.5kg m//s`
