Answer:
It will not change
Explanation:
The period of oscillation of a mass-spring system is given by
where
T is the period
m is the mass hanging on the spring
k is the spring constant
As we see from the formula, the period of oscillation does not depend on the amplitude of the motion: therefore, if we change the amplitude, the time for one oscillation will not change.
Answer:
Explanation:
The angle in rotational motion is given by:
Recall that the angular speed is larger than regular frequency (in rpm) by a factor of , so:
The wheel spins from rest, that means that its initial angular speed is zero(). Finally, we have to convert the given time to minutes and replace in the first equation:
