1. Write a formula for the final angle θf an object will be at when it starts at an initial angle θi and rotates with an angular velocity ω for a certain interval of time.
2. set the angle to zero, the angular velocity to 2.0 rad/s, and angular acceleration to be 0.30 rad/s2. Predict how fast the lady bug will rotate (wf) after 5.0 s.
An AC generator has 90 rectangular loops on its armature. Each loopis 15 cm long and 6 cm wide. The armature rotates at 1200 rpm about an axis parallel to the long side. If the loop rotates in a uniform magnetic field of 0.6 T, which is perpendicu..
