1) The flywheel of a steam engine begins to rotate from rest with a constant angular acceleration of 1.23 rad/s2. It accelerates for 22.7 s, then maintains a constant angular velocity. Calculate the total angle through which the wheel has turned 57.7 s after it begins rotating. Hint:This is rotational motion, with equations for angles similar to those for linear motion. Note that the TOTAL time is given. Answer: ______ deg. 2) A proposed space station includes living quarters in...
