Next step is to substitute the equation for the time t into the second equation of motion s=ut + at2/2 to obtain:
s = u[(v-u)/a] + a [(v-u)/a]2 /2
or s = u(v-u)/a + (v-u)2 /2a
or s =[2u+v-u](v-u)/2a
or s = (u+v)(v-u)/2a = (v+u)(v-u)/2a
or s= (v2-u2)/2a
or 2as = v2 –u2
or v2 –u2 = 2as
or v2 = u2 + 2as and this equation of motion can be used to find the final velocity or the distance travelled if the other values are given.
