Question

What is the angular acceleration at t=2.0 seconds?

A. 1.2rad/s^2

B. 1.6rad/s^2

C. 2.8rad/s^2

D. 3.2rad/s^2

Answer 1

The angular acceleration at t=2.0 seconds is 1.0 rad/s².

Step-by-step explanation:

The angular acceleration can be calculated using the formula:

angular acceleration = (final angular velocity - initial angular velocity) / time

Given that the initial angular velocity is 3 rad/s and the final angular velocity is 8 rad/s, and the time is 5 seconds, we can plug in these values to calculate the angular acceleration:

angular acceleration = (8 rad/s - 3 rad/s) / 5 s = 1.0 rad/s²

Therefore, the angular acceleration at t=2.0 seconds is 1.0 rad/s².
