Wheel A has a radius of 0.5m and Wheel B has a radius of 0.25m. Both wheels are turning at 200 rpm
and 100 rpm (revolutions per minute) each, when we simultaneously apply a brake to them, remaining at
rest in 10s and 20s respectively. Find the frequency of each wheel. Find the initial angular velocity of
each wheel. The angular acceleration of each wheel. Find the time that both wheels will be turning with
the same angular velocity. Find the angular velocity of both wheels at the time found above. Find
for the previous time, the value of the tangential acceleration at a point located on the periphery of both wheels.
Find for the previous time the value of the centripetal acceleration at a point located on the periphery of both
wheels. When the wheels are stopped, what total angle will it have turned from the moment we apply
the breaks?​
