Question

Derive the expression​

Answer 1

Answer:

Step-by-step explanation:

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

S = ut + 1/2at2__________(1)

v = u + at _____________ (2)

t = (v – u)/a

Substitute the value of t in equation (1)

S = ut + 1/2at2

2aS = 2u(v−u) + (v−u)2

2aS = 2uv − 2u2 + v2 − 2uv + u2

2aS = v2 − u2

v2 = u2 + 2aS

Answer 2

Step-by-step explanation:

{v-u}{v+u}=2as

i I think this is the half question
