What is the turntable’s angular velocity at t = 4.0s ?

did I miss something?

there is a graph x axis goes from 0-4 t(s) and y axis 0-5 (rad/s^2)

it starts out at 0,5 then drops down to 2,0 and stays 3,0 4,0

To determine the turntable's angular velocity at t = 4.0s, we would need to know the equation that describes the angular position of the turntable as a function of time. Without that information, it is not possible to find the exact value of the angular velocity at t = 4.0s.

However, if you have the equation for the angular position as a function of time, we can differentiate it to find the angular velocity. The angular velocity is given by the derivative of the angular position with respect to time.

If the equation is given by θ(t), then the angular velocity ω(t) is given by:

ω(t) = dθ(t)/dt

By substituting t = 4.0s into the equation, you can calculate the angular velocity at that particular time.

To determine the turntable's angular velocity at t = 4.0s, you need to know how the angular velocity changes over time. Angular velocity is usually denoted by the symbol ω (omega) and is defined as the rate of change of angle with respect to time.

If you have a function that describes how the angular velocity changes over time, you can simply substitute t = 4.0s into the function to find the value of ω at that time. However, without any additional information or equations, it is not possible to give a specific answer to this question.

To obtain the angular velocity at t = 4.0s, you need to consider if there are any additional details or equations given in the problem statement.
