If the total energy transferred to a surface in time $t$ is $6.48 \times 10^5 \,J$, then the magnitude of the total momentum delivered to this surface for complete absorption will be:

• A
  $2.46 \times 10^{-3} \,kg \cdot m/s$
• B
  $2.16 \times 10^{-3} \,kg \cdot m/s$
• C
  $1.58 \times 10^{-3} \,kg \cdot m/s$
• D
  $4.32 \times 10^{-3} \,kg \cdot m/s$
