A janitor opens a $1\mathrm{.}50$ m wide door by pushing on it with a force of $40\mathrm{.}5$ N directed perpendicular to its surface.

HINT

$($a$)$

What magnitude torque $($in N $$ m$)$ does he apply about an axis through the hinges if the force is applied at the center of the door?

Your response differs from the correct answer by more than $10\%.$ Double check your calculations. N $$ m

$($b$)$

What magnitude torque $($in N $$ m$)$ does he apply at the edge farthest from the hinges?
