The angle theta through which a disk drive turns is given


The angle θ through which a disk drive turns is given by θ(t)=a+bt-ct3, where a,b and care constants, t is in seconds, and θ is in radians. When t=0,θ=Π/4rad and the angular velocity is 2.10rad/s , and when 1.60s , the angular acceleration is 1.40rad/s2

What is the angular velocity when the angular acceleration is 3.70rad/s2 ?
