A fan blade,initially at rest,rotates with a constant acceleration of 0.025 rad/s².What is the time interval required for it to reach a 6.50-rad displacement after starting from rest? A)3.61 s B)260 s C)0.163 s D)22.8 s

Question

Quizplus · Accepted Answer

The time interval can be calculated using the equation for angular displacement under constant angular acceleration: θ = 0.5 * α * t². Solving for t when θ = 6.50 rad and α = 0.025 rad/s² gives t = √(2*6.50/0.025) = 22.8 s.
