Answer: 875.762 N
Explanation:
Given
[tex]mass of car(m_c)=1120 Kg[/tex]
[tex]Mass of boat +trailer(m_{bt}) =742 Kg[/tex]
Car exerts a force of 1898 N
[tex]Acceleration of system\left ( a\right ) is 0.549 m/s^2[/tex]
Therefore Force Equilibrium of system
[tex]F_{car}-f_{resist}=\left ( m_c+m_{bt}\right )a[/tex]
[tex]f_{resist}=1898-\left ( 1120+742\right )\left ( 0.549\right )[/tex]
[tex]f_{resist}=1898-1022.238=875.762 N[/tex]
