In a warehouse, a 30.0-kg wooden crate is placed on a sturdy table. A 20.0-kg metal box is then placed on top of the wooden crate as shown. Determine the normal force that the table exerts on the wooden crate and the normal force that the wooden crate exerts on the metal box.

• A. $N_{\text{table }}=30\mathrm{\ N},\ N_{\text{crate }}=294\mathrm{\ N}$
• B. $N_{\text{table }}=196\mathrm{\ N},\ N_{\text{crate }}=20\mathrm{\ N}$
• C. $N_{\text{table }}=294\ N,\ N_{\text{crate }}=490\mathrm{\ N}$
• D. $N_{\text{table }}=490\ N,\ N_{\text{crate }}=196\ N$
