Question

The angle through which a rotating wheel has turned in time t is given by θ = a t− b t2+ c t4, where θ is in radians and t in seconds.

A)Determine an expression for the instantaneous angular velocity ω if t is in seconds.

ω = ______ rad/s

B)Determine an expression for the instantaneous angular acceleration α if tis in seconds.

α = _______ rad/s^2 c)If a = 9.0 rad/s , b = 14.5 rad/s2 , c = 1.5 rad/s4 , evaluate ω at t = 3.2 s . ω = _____ rad/s d)Evaluate α at t = 3.2 s . α = ______ rad/s^2 e) What is the average angular velocity between t = 2.0 s and t =3.2 s ? ωavg = _______ rad/s f)What is the average angular acceleration between t = 2.0 s and t =3.2 s ? αavg = ____ rad/s^2
