This is more of a physics question, but since I have expertise in that subject as well so that means I can assist you. First of all, were you able to get it started?
Our teacher hasn't discussed this yet so I have no idea how to solve this.
What forces do you think act on the body?
Gravitational force, right? Which is the weight, and it usually acts vertically downward. when you have a string, there is usually tension which acts away from the body being pulled since it is only one string, the tension will be the same let's resolve the weight of 5g
Oh, in this problem, friction is disregarded.
no, we only have to resolve the weight along the plane for us to do that we need the angle marked in green it will be 20 because it is usually the same as the angle of the plane
ok. then what should i do?
