Answer:
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.
Answer:
Explanation:
Work is the product of force and displacement. Work is positive if force and displacement moves in the same direction. Work is negative if force and displacement moves in opposite direction. Take for example, a load is to move from point A to point B in the forward direction. if you apply force on the load from point A to B work done on the load is positive. If it happens that the force you apply is to the opposite direction, the work done will be negative.
