A wheel rotating about a fixed axis with a constant angular acceleration of 3 rad/s starts from rest att 0. The wheel has a diameter of 20 cm. What is the magnitude of the total linear acceleration of a point on the outer edge of the wheel at t = 4 s?
Added by Rocio S.
Step 1
First, we need to find the angular velocity (ω) at t = 4 s. We know that the initial angular velocity (ω₀) is 0 rad/s, the angular acceleration (α) is 3 rad/s², and the time (t) is 4 s. We can use the formula: ω = ω₀ + αt Show more…
