Question

 During the spin cycle the time dependent angular speed of a washing machine drum is given by the equation ω(t) = at + bt2 - ct4 where a = 1.1 rad/s2, b = 0.25 rad/s3 and c = 0.045 rad/s5. At time t = 0 s, a point P on the washer drum is located at θ0 = 1.9 rad.

a. Write an equation for the angular acceleration of the drum, as a function of time, in terms of the given parameters. 

b. What is the angular acceleration, in radians per square second, at time t = 2.5 s? 

c. Write an equation for the angular position of the point P, as a function of time, in terms of the given parameters.
