To make t the subject of the formula S = ut + 12at^2:
1. Move the ut term to the other side by subtracting ut from both sides of the equation:
S - ut = 12at^2
2. Factor out t from the right side of the equation:
S - ut = t(12a - u)
3. Divide both sides of the equation by (12a - u) to isolate t:
t = (S - ut) / (12a - u)
After simplification, the equation becomes:
t = S / (12a - u) - u / (12a - u)
Therefore, none of the options A, B, C, or D accurately represents t as the subject of the formula S = ut + 12at^2.
