Given
mass of rock
diameter of circle
radius
At highest Point
At highest Point N=0 because mass is just balanced by centripetal Force
thus
<h2>Answer: 540 J</h2>
Explanation:
The Work done by a Force
refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path.
Now, when the applied force is constant and the direction of the force and the direction of the movement are parallel, the equation to calculate it is:
(1)
In this case both (the force and the distance in the path) are parallel (this means they are in the same direction), so the work performed is the product of the force exerted to push the box
by the distance traveled
.
Hence:
(2)
