Question

prove third equations of motion by alzebric method​

Answer 1

✒ v = u + at

✒ Squaring 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 of motion

✏ v² = u² + 2as

Answer 2

Explanation:

Newton's third law of motion :- according to " sir issac NEWTON", Action and reaction are of equal magnitude and directed in opposite direction. It means if you apply force on a body then body must apply force on you. Then according to NEWTON's 3rd law body must apply force
