A small boy is trying to open a 50 kg door with a height of 2 meters and a width of 75 centimeters. If he applies a force of 5 Newtons at the door handle (5 cm from the edge), how long will it take to open the door so that it's completely open (perpindicular to when it was closed)?

torque= I * acceleration.

torque= .75*5
I= 1/3*50*.75^5

solve for acceleration.
