Homework Statement
During a certain period of time, the angular position of a swinging door is described by θ = 5.00 + 10.0t + 2.00t2, where θ is in radians and t is in seconds. Determine the angular position, angular speed, and angular acceleration of the door (a) at t = 0 and (b) at t = 3.00 s.
Homework Equations
ω = dθ / dt
α = dω / dt
The Attempt at a Solution
a) θ = 5.00
ω = 5 / 0
α = dω / 0
This just doesn't make sense, you cannot divide by 0.
But the other formulas, have either both ω and α or t cancels everything out.
This is supposed to be a simple problem of instantaneous angular speed and acceleration, how am I over complicating this?
