A discus thrower starts from rest and begins to rotate with a constant angular acceleration of 2.5 rad/s2 . Part A:How many revolutions does it take for the discus thrower's angular speed to reach 6.3 rad/s ? Part B: How much time does this take?
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...
