Homework Statement
Suppose a revolving door at the bank is spinning around once every 4 seconds. As you walk through, you push on the door for 3 seconds, which increases the rotational speed so that it rotates once a second. What wat the rotational acceleration due to your push?
Homework Equations
This is what I have so far...
The Attempt at a Solution
Acceleration-90/4=22.5
Displacement-360/3=120
22.5 + 120= 140.5 rev/s
