Question

Can you please show me how to get the answer for both of these?

1. Set the angle to 5 radians and the angular acceleration to zero. Set the angular velocity to 3.5 rad/s. Predict the angle at which the ladybug will be at after 4.5 s. (Show your calculations.)

2. Setup the same scenario you had in #1, but set the angular acceleration to be 0.30 rad/s². Predict how fast the ladybug will rotate (ω_f) after 5.0 s. (Show your calculations.)

Definition Definition Rate of change of angular velocity. Angular acceleration indicates how fast the angular velocity changes over time. It is a vector quantity and has both magnitude and direction. Magnitude is represented by the length of the vector and direction is represented by the right-hand thumb rule. An angular acceleration vector will be always perpendicular to the plane of rotation. Angular acceleration is generally denoted by the Greek letter α and its SI unit is rad/s 2 .
