Use the formula a = v2 / r, with v = velocity (speed, actually) in meters/second, r = radius in meters. The answer will be in meters per square second.

What is the centripetal acceleration of an object being swung on a string with a radius of 3 meters at a velocity of 4 meters per second?
Use the formula for centripetal acceleration: velocity squared / radius.
What does and acceleration of five meters per second squared mean about the velocity of the object?
It means that the object's speed is always 5 meters per second faster than it was one second earlier.
An object traveling at a constant 20 miles per second in a circular path is changing what?
This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.This object is changing its position, its velocity, and its acceleration.
An object's velocity changes from 30 meters per second to 23 meters per second in 3 seconds What is is its acceleration?
-2.33 metres per second squared
If a trucks brakes are applied for 2 seconds giving it acceleration of -3.1 ms2 what will the trucks new speed be in ms?
No starting velocity was given, so I can't give a correct answer, but I can answer part of the question. Given an acceleration and a time through which an object accelerates, you can determine the change in velocity. Acceleration is just the change of velocity over a period of time. Since we have an acceleration of -3.1 meters per second squared, acting for two seconds, we have a change in velocity of -6.2 meters per second. Take the original velocity and subtract 6.2 meters per second to get the answer.

Use the formula for centripetal acceleration: velocity squared / radius.
What agents would cause a change in centripetal acceleration?
Centripetal Acceleration is the ratio of the square of the velocity and radius ac=v2/r So if we change the velocity of the circulating object or change the radius of the revolution, centripetal acceleration is changed
How does centripetal acceleration depend upon the object's speed and the radius of the circle?
The centripetal acceleration is equal to velocity squared over radius. a=v^2/r
What is meant by centripetal acceleration is perpendicular to velocity?
As an object goes round in a circular path, then its velocity will along the tangent at that instant. But centripetal acceleration is normal to that tangent and so along the radius of curvature. As acceleration is perpendicular to the velocity, the direction aspect is ever changing and so the object goes round the circular path.
Why does centripetal acceleration occur?
Centripetal means towards the center. Any object moving around in a circle is accelerating towards the center. Remember that acceleration involves a change in velocity, and a specification of "velocity" includes the direction; therefore, since the direction of the movement changes continuously, the object is "accelerating", according to the definition of acceleration.
If an object has only a centripetal acceleration what aspect of the object's velocity is changing?
Only the direction of the velocity vector is changing. The magnitude (speed) is constant. Its motion is in a closed circular path.
When An object speeds up it has what acceleration?
For an object's speed to change (increase or decrease), the object must be accelerating. If there is an acceleration, there is a non-zero net force acting on the object.note: Velocity and speed are different. An object's velocity can change without the speed changing. Example of this is centripetal acceleration. The object's velocity changes directions, thus the velocity changes. The magnitude (or speed), however, stays the same (if only a radial acceleration is present).
What is the acceleration toward the center of a curved or circular path is called what acceleration?
That's called 'centripetal acceleration'. It's the result of the centripetal forceacting on the object on the curved path.
What is the acceleration of an object?
When a net force acts on that object, there is a change in velocity, and thus acceleration.
He constant acceleration of an object moving in a circle is called?
centripetal acceleration
What are the significant similarities and differences between velocity and acceleration?
The differences are that acceleration refers to the rate of change in velocity of an object while velocity is the rate of displacement of an object, and acceleration is measured in meters per squared seconds while velocity is measured in meters per second. On the other hand, they both use time as a component and they are both vectors in nature.
What indicates the acceleration of an object?
Velocity. A change in VELOCITY will always indicate the acceleration of an object.
