Q. 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 is recorded as
A) $17.565\ kg\ ms^{- 1}$
B) $17.56\ kg\ ms^{- 1}$
C) $17.57\ kg\ ms^{- 1}$
D) $17.6\ kg\ ms^{- 1}$
Explanation
(d) In terms of three significant figure
Momentum$\ P = mv = 3.513 \times 5.00 = 17.6$
