Question

drive the equation v = u +at
​

Answer 1

$\huge{\underline{\mathtt{\blue{A}\red{N}\pink{S}\green{W}\purple{E}\orange{R}}}}$

Explanation:

By the defination of acceleration

a=v-u/t

at=v-u

v=u+at

Hence derived

Answer 2

ANSWER -

Consider a body having initial velocity 'u'. Suppose it is subjected to a uniform acceleration 'a' so that after time 't' its final velocity becomes 'v'. Now, from the definition of acceleration we know that:

Acceleration =

Time taken

Change in velocity

or Acceleration =

time taken

Final velocity- Initial velocity

So, a=

t

v−u

at=v−u

and, v=u+at

where v= final velocity of the body

u= initial velocity of the body

a= acceleration

and t= time taken
