So, <u>their net force on the cart is 10 N to the right</u>.
<h3>Introduction</h3>Hi ! Here, I will help you with the net forces (results of forces) acting on a two-dimensional area and in opposite directions. Steps that can be taken are as follows :
- Determine where the force will go, the important thing is that you are consistent until the end.
- Count the values of the force acting, the force against the direction of your mind in number 1 is given a negative sign.
- Look at the results, if it's marked (-), then choose the opposite direction from your thoughts at number 1.
The equation for calculating the net force from this two-dimensional straight line is as follows:
With the following condition :
= net force (N)
= first force and its direction (N)
= second force and its direction (N)
= You can add up the force values as many times as the question (N).
We know that :
In my mind, I determined that the force will go to the right. So :
= John's force = -7 N >> Because he is walked to the left.
What was asked :
Step by step :
The movement of the cart is to the right because the net force value that I calculated is not opposite (with negative sign) to the right direction. So, their net force on the cart is 10 N to the right.
