Answer:

Explanation:

Given mg = 4N .

m = 4 / g

At the bottom of the swing let centripetal acceleration be a

T - mg = ma

9 - 4 = ma

5 = 4 a  / g

a =  5g / 4

Given the diagram provided, we can confirm that the object will accelerate in a downward direction.

<h3>Why will it accelerate downwards?</h3>

The free-body diagram shows us the forces that are acting on this object. Through this diagram, we can see that the forces on the left and right of the object are balanced, meaning that there will not have movement in either of these directions.

The diagram shows that the downward force being applied is not balanced by an opposite force, so the object will accelerate in this direction.

Therefore, we can confirm that object will accelerate in a downward direction due to its downward force not being balanced by an opposing force.

An upward force is applied to a 6.0–kilogram box. This force displaces the box upward by 10.00 meters. What is the work done by
enyata [817]
We know that work= force x displacement along the direction of force
here force shoukd be equal to its self-weight.
thus, work= self-weight x displacement.
=mass x acceleration due to gravity x displacement.
= 6kg x 10m/s^2 x 10
60x10
=600J
