Question

Can somebody explain me how he found the effective equation of motion?

Answer 1

These equations of motion are valid only when acceleration is constant and motion is ... This I can say with absolute metaphysical certainty. .... This gives us the velocity-time equation.

Answer 2

Hola mate !! ✨✨

here's your answer ....⬇️⬇️

The equations of motion are valid only if ...

➡️the acceleration is uniform

➡️motion is in a straight line .

the above points confirm that the motion of the object should be uniform.

hope it helps !! ❤️❤️
