Karla Fitzpatrick · Answer 1

We have the following equation:

s = ut + 1 / 2at ^ 2

Clear a for the equation:

1 / 2at ^ 2 = s-ut

at ^ 2 = 2s-2ut

a = 2s / t ^ 2-2ut / t ^ 2

Rewriting:

a = (2s-2ut) / (t ^ 2)

Answer:

An equation that represents a in terms of other variables is:

C. 2s-2ut / t ^ 2
