Solution

The correct option is A
$17.6 k g m s^{- 1}$

Step 1. Given data
Mass of the body, $m = 3.513 k g$
Speed of the body, $v = 5 m s^{- 1}$
Step 2. Finding the momentum, $P$
By using the formula of the momentum
$P = m v$
$P = 3.513 \times 5$
$P = 17.565 k g m s^{- 1}$
By rounding off,
$P = 17.6 k g m s^{- 1}$
Hence, the correct option is $(A)$ .
