1. The problem statement, all variables and given/known data The uniform 3.6m pole is hinged to the truck bed and released from the vertical position as the truck starts from rest with than acceleration of 0.9m/s^2. If the acceleration remains constant during the motion of the pole, calculate the angular velocity of the pole as it reaches the horizontal position. Diagram attached. 2. Relevant equations I believe these equations are relevant, however, I am not given a mass for the pole, so i'm not entirely sure. a(tangential)=mrθ'' a(normal) = mrω^2 ƩMo=Iθ''+Ʃma(vector)d I=k^2m ω=2Vx ω=(ωo^2+2aθ)^(1/2) 3. The attempt at a solution So I eventually want to realise the angular velocity ω. I have done a similar question that utilised energy and momentum methods, however, with a negligible mass, i'm not sure whether that will affect the equations, since the example question used mass. So essentially, I believe it may be using the last formula I provided, since it is not determined by time or mass. So, all I need to find is the acceleration, since I already know that ωo is at rest, and θ=90. Finding the acceleration, from the given positive direction of acceleration of the truck body, is something that I can't figure out. Thankyou for any feedback!
