now I've gotten teh total angle the wheel turned between t=0 and the time it stopped, but i can't work out

a) what tiem the wheel stops; or

b) the angular deceleration after 2.3 s

i tried using omega = omega_0 + alpha_deceleration* t and 2*alpha_deceleration* (theta-theta_0) = omega^2-omega_0^2, using final omega = 0.

but this ended up with an end time of 315.3 seconds... which was wrong...

help if u can please
