Exclamation I'm having trouble solving this Dynamics problem




R=3m
Vo=1.5 m\s
epsilon=0.5
rad\s^2
omega=2 rad\s

I need to find the Absolute Velocity when the person walks to the end of the circle (radius)

Not sure what epsilon is supposed to represent - is it the radial acceleration of the wheel? If so, then use the general equation for velocity in a rotating frame:

$\vec v = \dot r \hat r+ r \omega \hat \theta $

Here the rotational velocity omega varies with time:

$\omega(t) = \omega_o + \epsilon t $

Hope this helps.
