An object is swung in a horizontal circle on a length of string that is 0.93 m long. Its acceleration is 26.36 m/s2. What is the time it takes the object to complete one horizontal circle? P. S. : I know the answer is 1.18 seconds but I just don’t know how to get there. Can someone explain to me how to do it? Thanks

The object takes approximately 1.180 seconds to complete one horizontal circle.  

Explanation:

From statement we know that the object is experimenting an Uniform Circular Motion, in which acceleration (), measured in meters per square second, is entirely centripetal and is expressed as:

(1)

Where:

- Period of rotation, measured in seconds.

- Radius of rotation, measured in meters.

If we know that and , then the time taken by the object to complete one revolution is:

The object takes approximately 1.180 seconds to complete one horizontal circle.  

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )
