A wheel rotating about a fixed axis has a constant angular acceleration of 4.0 rad/s2. In a 4.0-s interval the wheel turns throu
Nady [450]

Answer:

The  time interval is  t =  3 \ s

Explanation:

From the question we are told that

    The angular acceleration is  \alpha  =  4.0 \ rad/s^2

     The  time taken is  t  =  4.0 \ s

      The angular displacement is  \theta  = 80 \ radians

     

The angular displacement can be represented by the second equation of motion as shown below

          \theta =  w_i t  +  \frac{1}{2} \alpha t^2

where  w_i is the initial velocity at the start of the 4 second interval

So substituting values

        80 =  w_i *  4 + 0.5 *  4.0 *  (4^2)

=>    w_i  =  12 \ rad/s

Now considering this motion starting from the start point (that is rest ) we have

       w__{4.0 }} =  w__{0}} +  \alpha  * t

Where  w__{0}} is the angular velocity at rest which is zero  and  w__{4}} is the angular velocity after 4.0 second which is calculated as 12 rad/s s

        12 =  0  + 4 t

=>       t =  3 \ s

Answer:

e see that the distances are different, the only way that the two beams of light approach simultaneously is that event 2 (farthest) occurs first than event 1

Explanation:

This is an ejercise in special relativity, where the speed of light is constant.

Let's carefully analyze the approach, we see the two events at the same time.

The closest event time is

       c = (x₁-300) / t

       t = (x₁-300) / c

The time for the other event is

       t = (x₂- 600) / c

since they tell us that we see the events simultaneously, we can equalize

        (x₁ -300) / c = (x₂ -600) / c

         x₁ = x₂ - 300

We see that the distances are different, the only way that the two beams of light approach simultaneously is that event 2 (farthest) occurs first than event 1
