Can we solve it using v = 2uv/u+v.How ?

I'm afraid this question is fundamentally flawed. Do you know much algebra?
Watch:
v = 2uv / (u + v)

uv + v^2 = 2uv

cancel v throughout (assume non-zero and therefore non-trivial solution)

u + v = 2u

hence v = u

I.e final speed = inital speed
This equation describes an object travelling with constant speed.


If you are referring to solving the differential equation of motion
F = ma there are multiple techniques, most of which involve calculus, specifically integration.
Ask your physics teacher, or ask a new question here with some additional info if you would like more help.

no we cannot solve this way / is divided by
average velocity = distance travelled / time

(u+v) / 2 = s/t

therefore s= (u+v) x t / 2

substituting value of eqation 1

s = (u+u+at / 2) t

s = (2u + at / 2) t

s = (2u x t )/ 2 + (at x t) / 2


s = ut + 1/2 a(t)2

No need to solve it, as motion will follow the path of least resistance by itself.

hey the equation is wrong...
RHS -- 2uv/u + v = 2v + v = 3V which is not equal to LHS...hence u cant solve it...as it is wrong...hence proved..lol

??????????????

Relax, calm down, take a deep breath...... Now, go back and try to formulate a complete, coherent question.

No, we cannot solve it.
