Answer:
The magnitude of the acceleration is at its maximum value.
Acceleration =
Explanation:
During simple harmonic motions such as the oscillation of a spring, at the two extremes of the motion, the acceleration of the mass becomes maximum. This is because this is the point where the force on the body is maximum.
The angular velocity
At points of maximum extension x, the maximum acceleration is given by the formula.
substituting in the value for , this implies that
⇒
Answer:
1.5min
Explanation:
To solve the problem it is necessary to take into account the concepts related to Period and Centripetal Acceleration.
By definition centripetal acceleration is given by
Where,
V = Tangencial velocity
r = radius
With our values we know that
Therefore solving to find V, we have:
For definition we know that the Time to complete are revolution is given by
