Answer 1

Answer:

every action has a equal & opposite reaction

Answer 2

We know that,

➪ v = u + at

➪ Squaring on both sides,

➪ v² = ( u + at )²

➪ v² = u² + 2uat + a²t²

➪ v² = u² + 2a (ut + 1/2 at²)

➪ From second equation of motion, we know that,

➪ (ut + 1/2 at²) = S

➪ v² = u² + 2aS

➪ Third equation ,

➪ v² = u² + 2as..
