Question

If s = u + 0.5at2, which equation is solved for t?

Answer 1

subtract u from both sides
0.5at^2 = s - u
divide both sides by 0.5a:
t^2 = 2(s - u)
------
a

t = sqrt [2(s - u)/ a]

Answer 2

thx !!

Answer 3

thats not a choice :/

Answer 4

what are the choices

Answer 5

t = square root of s minus u over 0.5 times a

t = square root of s plus u over 0.5 times a

t = square root of s minus u minus 0.5 over a

t = square root of s plus u minus 0.5 over a

Answer 6

the first one is the same as my answer

- dividing by 0.5 is the same as multiplying by 2

Answer 7

whoops! thanks a lot
