A body of mass $m=3.513 \mathrm{~kg}$ is moving along the $x$-axis with a speed of $5.00 \mathrm{~ms}^{-1}$. The magnitude of its momentum is recorded as
  1. $17.6 \mathrm{~kg} \mathrm{~ms}^{-1}$
  2. $17.565 \mathrm{~kg} \mathrm{~ms}^{-1}$
  3. $17.56 \mathrm{~kg} \mathrm{~ms}^{-1}$
  4. $17.57 \mathrm{~kg} \mathrm{~ms}^{-1}$

Solution

$ P=m v=3.513 \times 5.00 \approx 17.6 $
