Explanation:
v=u+at
at = v - u
And :
t = (v-u)/a
s = u(v-u)/a + 0.5at²
s = (uv-u²)/a + 0.5a*(v-u)²/a²
2as = 2uv-2u² + v² + u² -2vu
2as = v² - u²

Answer:
Frm second law of motion can be obtain by eliminating t between the first two equations of motion .
This is done as follows .
From second law of motion we have :
And from first equation of motion
This can be rearranged as ⤵
or
Putting the value of t in equation( 1) we get
proved .....
