Answer:
14.1 rad
Explanation:
Assuming constant acceleration, we can use kinematic equations to find the angular displacement as a function of the angular velocities and time.
Given:
ω₀ = 0 rad/s
ω = 31.4 rad/s
t = 0.8972 s
Find: Δθ
Δθ = ½ (ω + ω₀) t
Δθ = ½ (31.4 rad/s + 0 rad/s) (0.8972 s)
Δθ = 14.1 rad
