Answer:
Explanation:
initial angular velocity is ω₀ = 1 rad /s
angular acceleration α = - 0.5 rad /s²
time t = 2 s.
Let the initial angular position be θ .
angular displacement = 6 - θ . rad .
angular displacement = ω₀ t - 1/2 α t²
6 - θ = 1 x 2 - 0.5 x 0.5 x 2²
6 - θ = 2 - 0.5 x 0.5 x 2²
= 2 - 1 = 1
θ = 6 - 1 = 5
5 rad is the answer.
