Answer:
a. 3 s.
Explanation:
Given;
angular acceleration of the wheel, α = 4 rad/s²
time of wheel rotation, t = 4 s
angle of rotation, θ = 80 radians
Apply the kinematic equation below,
Given initial angular velocity, ω₀ = 0
Apply the kinematic equation below;
Therefore, the wheel had been in motion for 3 seconds.
a. 3 s.
