Question

displacement = at²+bt+c where a,b,c are constant. then prove that 4a(S-c) = v²-b²

pls help​

Answer 1

Answer:

Explanation:

x=At  ^2  +Bt+C…(i)

⇒v=2At+B

⇒v^2  =4A  2 t^2+4ABt+B^2  …(ii)

{By multiplying 4A in Eq. (i) }

4Ax=4A ^2t ^2+4ABt+4AC…(iii)

{from Eq. (i) and Eq. (iii)}

⇒v^2 −4Ax=B ^2  −4AC

⇒4Ax−v  ^2  =4AC−B  ^2
