Answer 1

Magnitude of momentum of the sparrow
`=0.23\ kg\ ms^(-1)`

Step-by-step explanation:

Given:

Mass of sparrow = 28 g =
`(28)/(1000)\ kg= 0.028\ kg`

Speed(velocity) of sparrow =
`8.1\ ms^(-1)`

Momentum of sparrow =
`mass* velocity = 0.028 * 8.1 = 0.2268\ kg\ ms^-1`

Momentum of sparrow in two significant figure can be given as
`=0.23\ kg\ ms^(-1)`
