a tire rolls from rest to an angular velocity of 6 radians per second. the angle it turns through is 12 radians. what is the ang
True [87]

Answer:

\alpha =1.5\ rad/s^2

Explanation:

Given that,

Initial angular velocity, \omega_i=0

Final angular speed, \omega_f=6\ rad/s

Angular displacement, \theta=12\ rad

We need to find the angular acceleration of the tire. We can find it using the third equation of rotational kinematics. So,

\omega_f^2-\omega_i^2=2\alpha \theta\\\\\alpha =\dfrac{\omega_f^2-\omega_i^2}{2\theta}\\\\\alpha =\dfrac{6^2-0^2}{2\times 12}\\\\\alpha =1.5\ rad/s^2

So, the angular acceleration of the tire is equal to 1.5\ rad/s^2.
