Answer:
Explanation:
As we know that tension force in the string will be equal to the centripetal force on the string
so we will have
now we have
now we have
now when string length is 0.896 m and its speed is 71.5 m/s then we will have

Answer:
The length of the incline is 3.504 meters.
Explanation:
Let suppose that Julietta's ball decelerates uniformly, then we determine the length of the incline is determined by the following equation of motion:
(Eq. 1)
Where:
- Length of the incline, measured in meters.
- Initial speed of the ball, measured in meters per second.
- Aceleration of the ball, measured in meters per square second.
- Time, measured in second.
If we know that ,
and
, then the length of the incline is:
The length of the incline is 3.504 meters.
