A propeller spins at 1880 rev/min.
the equals 197 rads/sec
b. What is the angular displacement of the propeller in 2.50 s ?

  • Physics -

    If you have angular velocity and you need angular displacement, just remember:
    velocity=displacement/time
    so solve that for displacement and it's
    displacement=velocity*time
    so it should be
    angular displacement=(197 rad/s)(2.5 s)
    and your answer should be 492.5 rad, be careful of whether the answer is supposed to be in degrees or radians
