For part a Torque T= F *r
T= 49.5 N * 1/2(1.14 m) =28.215 Nm
Sorry I'm still trying to find part b as well...
A man opens a 1.14-m wide door by pushing on it with a force of 49.5 N directed perpendicular to its surface.
(a) What magnitude torque does he apply about an axis through the hinges if the force is applied at the center of the door?
N · m
(b) What magnitude torque does he apply at the edge farthest from the hinges?
N · m

Ok here's part B:
T= F* r
T=1.14 m *49.5 cuz now theyre asking for the whole door not just the center
T= 56.43
