Question

find angular acceleration of the seet starting from rest if a clockwise of 10rad/s is applied to a arm ab​

Answer 1

Explanation:

discussed only uniform circular motion, which is motion in a circle at constant speed and, hence, constant angular velocity. Recall that angular velocity ω was defined as the time rate of change of angle θ:

ω

Δ

θ

Δ

t

where θ is the angle of rotation as seen in Figure 1. The relationship between angular velocity ω and linear velocity v was also defined in Rotation Angle and Angular Velocity as

v = rω
