Question

derive v2 = u 2 + 2as.​

Answer 1

Answer:

For getting the third law of motion equation, we use both of the equations of motion

S = ut + 1/2at2 and v = u + at, include the time variant t

t = v – u/a

and use this to replace t wherever it appears in the second equation. So

S=ut + 1/2at2 becomes

S = u(v – u/a) + 1/2a (v – u/a)2

= 2aS = 2u(v−u)+(v−u)2

= 2aS = 2uv − 2u2 − v2 − 2uv −u2

= 2aS = v2 − u2

= v2 = u2 + 2aS
