Answer:
The speed of the object at the lowest point in its trajectory is:
Explanation:
We can use the conservation of energy between the maximum point of swing and the lowest point of the pendulum.
(1)
Where:
- h is the height of the object at 30° with the vertical.
- v is the speed at the lowest point.
We can find h using trigonometry.
Now, using equation (1) we can find v.
