The angular velocity of the disk in figure 1 is ω = 4t2 + 3 rad/s, where t is in seconds. (a) (2 points) What is angular velocity and the magnitude of the (linear) velocity of point A on the disk when t = 0.5 s. (b) (3 points) Let θ be the counter-clockwise angle of point A from the horizontal x-axis. The derivative of the angle of A is the angular velocity of A, i. e. dθ dt = ω. Integrate the angular velocity to get an expression for the angle, θ. Use the condition that at t = 0, θ = 0 to solve for the integration constant. (c) (3 points) Differentiate the angular velocity with respect to time to get an expression for the angular acceleration, α(t).
