Figure gives angular speed versus time for a thin rod that rotates around one end. The scale

Question:

Figure gives angular speed versus time for a thin rod that rotates around one end. The scale on the w axis is set by wy = 6.0 rad/s.

(a) What is the magnitude of the rod's angular acceleration?

(b) At r = 4.0 s, the rod has a rotational kinetic energy of 1.60 J. What is its kinetic energy at t = 0?
