We are given that the gravitational pull of mars is 0.376 times the gravitational pull of the earth. The gravitational pull of the earth is:


g=9.8(m)/(s^2)

Now, we determine the gravitational pull of mars:


g_{\text{mars}}=0.376g

Substituting the value of "g" we get:


g_{\text{mars}}=0.376(9.8(m)/(s^2))

Solving the operation we get:


g_{\text{mars}}=3.68(m)/(s^2)

Now, to determine the weight of a person we use the following formula:


W=mg_{\text{mars}}

Where:


\begin{gathered} W=\text{ weight} \\ m=\text{ mass} \end{gathered}

Substituting the values we get:


W=(98.6\operatorname{kg})(3.68(m)/(s^2))

Solving the operation we get:


W=363.32N

Therefore, the weight of the person on mars is 363.32 Newtons.
