Answer:
The final position is -69.8 m
Explanation:
Recall that displacement is defined as:
[tex]displacement=x_f-x_i[/tex]
where [tex]x_f[/tex] represents the final position, and [tex]x_i[/tex] the initial position of the object (in our case 83.2 m). Since we also know the displacement (-153 m), we can solve the equation for the final position:
[tex]displacement=x_f-x_i\\-153=x_f-83.2\\-153+83.2=x_y\\x_f=-69.8\,\,m[/tex]
