What are the angular velocities at (a) t = 2.0 s and (b) t = 4.0 s? (c) What is the average angular acceleration for the time interval that begins at t = 2.0 s and ends at t = 4.0 s? What are the instantaneous angular accelerations at (d) the beginning and (e) the end of this time interval?

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). (d) (2 points) What is the angular acceleration and the magnitude of the (linear) acceleration of point A at t = 0.5 s. Figure 1: Problem 2
