2.23. Derive equation v2- u2 2as for uniformly accelerated motion

Answer»

from the first equation of motion, V = U + AT

Therfore, V - U = AT

We know that, S = (U + V / 2 )×T ∴ S/T = U + V / 2 ∴U + V = 2×S/T ∴ U + V = 2S / TSo Substituting eq1 and eq2, (V - U ) (V + U ) = AT ×2S/T ∴V² - U² = 2AS.
