angular acceleration is 0.2 rad/scounterclockwise.

The helicopter is in planar motion in the-plane. At the instant shown, the position of its center of massis=2m,=2.5m, its velocity is=12+4(m/s), and its acceleration is=3+5(m/s). The position of pointwhere the tail rotor is mounted is=?3.5m,=4.5m. The helicopter’s angular velocity is 0.3 rad/s clockwise, and its angular acceleration is 0.2 rad/scounterclockwise.
