The 1st one goes two added sodoes the second one then the third goes to removed then the fourth goes to added and the rest go to removed
I don’t see any picture sorry I wish I can help tho
Potential Energy = mass x gravitational acceleration x height
potential Energy = 1 x 9.8 x 10 = 98 joules
To look for displacement, just draw a vector from your beginning stage to your last position and settle for the length of this line. So we begin by drawing a line to the north which is 30 ft, since it is north, the line is going up, then it move 5 ft to the south, so put a line going down, so we are in 25 ft, North so that would be the answer.
The answer is d.heuristic
