A car mechanic mounts a car on the repair stand and starts the rear wheel spinning from rest to a final angular velocity of 275 rpm in 7.00 s. Calculate the average angular acceleration in rad/s2

Homework Answers

Answer #1

Formula used :

Average angular acceleration =

final angular velocity

initial angular velocity

t = time interval for change.

Solution:

Given :

Final angular velocity =275 rpm =28.8 rad/s

Initial angular velocity = 0

time taken =7.00 s

So
