1. CH. 9 (50 points) An airplane propeller speeds up in its rotation with uniform angular acceleration α=1256.00 rad/s2. It is rotating counterclockwise and at t=0 has an angular speed of ωi=6280.00rad/s. STUDY THE DIAGRAM CAREFULLY. (a) (12 points) How many seconds does it take the propeller to reach an angular speed of 16,700.00rad/s ? (b) (12 points) What is the angular speed (in rad/s ) at t= 10.00 seconds? (c) (14) What is the instantaneous tangential speed V of a point p at the tip of a propeller blade (in m/s ) at t=10.00 seconds? See the diagram above. (c) (12 points) Through how many revolutions does the propeller turn in the time interval between 0 and 10.00 seconds?
