Answer:
1.) Force of friction on the cart pointing towards the left
2.) The force of tension of the rope on the cart pointing towards the right
3.) Normal force of the surface on the cart pointing up
4.) Gravitational force of the Earth on the cart pointing downwards
5.) If the cart is not moving, then the friction force acting on the cart must be equal than the tensile force that acts on the cart.
This can be explained using Newton’s First Law: An object at rest will remain at rest, and an object an motion will remain in motion unless acted upon by another force.
(However you’re really only looking at the first part)
Explanation:
Hmm, it is a little difficult to see since the top of the picture is cut off.
There are a few things I will assume:
1.) There is a cart attached to a rope/string, with no other object present other than the weight on the right
2.) You are working with friction
