Which is a characteristic of centripetal acceleration?
2 answers:
Answer:
It is directed inward, toward the center of a circle.
Explanation:
Centripetal acceleration is the acceleration resulting from a movement along a circular path.
This acceleration is always directed towards the center of the circle and is defined as follows:
where is the tangential velocity of the object in the circular path, and
is the radius of the circle.
So the answer is:<u> It is directed inward, toward the center of a circle.</u>

Given data:
* The mass of the baseball is 0.31 kg.
* The length of the string is 0.51 m.
* The maximum tension in the string is 7.5 N.
Solution:
The centripetal force acting on the ball at the top of the loop is,
For the maximum velocity of the ball at the top of the vertical circular motion,
where g is the acceleration due to gravity,
Substituting the known values,
Thus, the maximum speed of the ball at the top of the vertical circular motion is 4.16 meters per second.
