lots of questions
1) a 2N and 6N force pull on an object to the right and a 4N force pulls to the left a 0.5 kg object what is the net force on the object

2)a 20mkg bike accelerates at 10m/s2 with what force was the person pedaling

3)if a person is pushing a cart with a force of 40 newtons and it accelerates at 0.5 m/s2 what is the mass of the cart

4)what is the acceleration of a 3 kg rock that is thrown with a force of 18N

These are not difficult questions. You are going to have to make an effort if you expect to learn physics.
I or someone will be around to critique your thinking.
