A body of mass m =3.513 kg is moving along the X-axis with a speed of 5.00 ms^(-1)The magnitude of its momentum as recorded is :

Answer»

`17.57 kg ms^(-1)`
`17.6 kg m^(-1)`
`17.565 kg m^(-1)`
`17.56 kg ms^( -1)`

Solution :Here`P = m UPSILON = 3.513 XX 5.00`
`= 17.565 kg ms^(-1) = 17. 6 kg ms^(-1)`
:’ answer should have three SIGNIFICANT figs
Hence (B) is the correct choice.
