Physics

At t=0t=0 the current to a dc electric motor is reversed,resulting in an angular displacement of the motor shaft given byθ(t)=(θ(t)=( 260 rad/srad/s )t−()t−( 20.5 rad/s2rad/s2 )t2−()t2−(1.49 rad/s3rad/s3 )t3)t3.

A- At what time is the angular velocity of the motor shaftzero?

B- Calculate the angular acceleration at the instant that themotor shaft has zero angular velocity.

C- How many revolutions does the motor shaft turn throughbetween the time when the current is reversed and the instant whenthe angular velocity is zero?

D- How fast was the motor shaft rotating at t=0t=0, when thecurrent was reversed?

E- Calculate the average angular velocity for the time periodfrom t=0t=0 to the time calculated in part A.
