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
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
