At its lowest setting a centrifuge rotates with an angular speed of 1 250 rad s When it is switched to the next higher setting it takes t 9 5 s to uniformly accelerate to its final angular speed 2 750 rad s A) Calculate the angular acceleration of the centrifuge 1 in rad s 2 over the time interval t B) Calculate the total angular displacement (in radians) of the centrifuge, , as it accelerates from the initial to the final speed

Question: At its lowest setting a centrifuge rotates with an angular speed of 1 = 250 rad/s. When it is switched to the next higher

At its lowest setting a centrifuge rotates with an angular speed of ω ₁ = 250 rad/s. When it is switched to the next higher setting it takes t = 9.5 s to uniformly accelerate to its final angular speed ω ₂ = 750 rad/s.

A) Calculate the angular acceleration of the centrifuge α ₁ in rad/s ² over the time interval t.

B) Calculate the total angular displacement (in radians) of the centrifuge, Δθ, as it accelerates from the initial to the final speed.
