Physics

The propeller of a plane has a rotational inertia of 890kg*m². Each blade has a length of 3.3 m. The propellorstarts from rest and reaches a final angular speed of 16 rad/s inonly 8 seconds.
a) What was the angular acceleration of thepropeller?
b) What was the net torque exerted on the propellerwhile it was accelerating?
c) When t = 4 s, what was Ï‰ for thepropeller?
d) When t = 4 s, through what angle Î¸had the propeller rotated? Your answer should be entered inradians.
e) When t = 4 s, determinea_c for the tip of a blade.
f) When t = 4 s, determinea_tan for the tip of a blade.
g) When t = 4 s, determinea_tot for the tip of a blade.
Thank you for your help!
