Answer:
1st t=d/s
2nd s=d/t
5th d=st
are all of the variations I came up with
Explanation:
the original formula for speed is s=d/t
then, I created a ratio of s/1=d/t and cross multiplied to find d=st
then, I isolated the t in one side by dividing by s on both sides.
That is -300 J, because the work = the force times the distance. When the distance is a positive value when it is going down, the distance is a negative value when it is going up. The only thing that change is the minus, the absolute value of the work remains the same
