The net vertical force on a box F as a function of the vertical position y is shown below.

W = 0 J

Explanation:

Formula for work done is;

W = F × d

Where;

W is work done

F is Force

d is distance covered

What this means is that we will calculate the area under which the given times in the graph pass.

Thus;

At constant force of F = 40 N which falls in between distance of 0 m and 2m,

W1 = 40 × 2 = 80 J

At constant force of -20 n which will fall between distance of 2 m and 6 m which is 4m, we have;

W2 = -20 × 4

W2 = -80 J

Thus, total workdone is;

W = W1 + W2

W = 80 - 80

W = 0 J

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.
