Question

A body of mass `m = 3.513 kg` is moving along the x-axis with a speed of `5.00ms^(-1)`. The magnetude of its momentum is recorded as
A. (a) `17.6kgms^(-1)`
B. (b) `17.565kgms^(-1)`
C. (c) `17.56kgms^(-1)`
D. (d) `17.57kgms^(-1)`

Answer 1

Correct Answer - A
(a) Momentum, `p = m xx v`
`= (3.513) xx (5.00) = 17.565 kgm//s`
`=17.6` (Rounding off to get three significant figures)
