Jose pushes a cart with a force of 12 N to the right. Lucy also pushes the cart with a force of 5 N to the right. John pushes the cart with a force of 7 N to the left. What is my net force on the cart?

So, their net force on the cart is 10 N to the right.

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 :

The equation for calculating the net force from this two-dimensional straight line is as follows:

With the following condition :

We know that :

In my mind, I determined that the force will go to the right. So :

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.

1) estimating temperature to the nearest tenth of a degree

2) estimating the mass of the sample to the nearest tenth of a gram

4) the position of the cups of sand and water under the heat lamp
