Someone please help me with this physics problem!

[From: ] [author: ] [Date: 11-08-09] [Hit: ]
Power = W/s = 26.4/2.......
A person opens a door by applying a 14-N force perpendicular to it at a distance 0.90 from the hinges. The door is pushed wide open (to 120 degrees ) in 2.4 s .

1) How much work was done?

2) what was the average power delivered?

-
Work = Torque * radians = 14*0.9*120degrees*2pi radians/360degrees = 26.4J
Power = W/s = 26.4/2.4 = 11watts
