You have two equations describing motion: v = u + at and s = ut + 0.5at². If you know the initial velocity u, the final velocity v, and time t, but not acceleration a or displacement s, how would you solve for s?

Solve for a in v = u + at and substitute into s = ut + 0.5at².

Assume a value for a and solve both equations separately.

Use graphical methods to determine s.

Substitute v = u + at into s = ut + 0.5at² to eliminate a.
