Question

(a) Derive the formula : v= u + at, where the symbols have usual meanings.​

Answer 1

Answer:

there are two ways

t=time

a= acceleration

v=velocity

u=initial velocity

a=(v-u)/t

at=v-u

at+u=v

Therefore v=u+at

Explanation:

Consider the graph attached below:

The linear motion of a body with initial velocity - u

The body accelerates uniformly with  - a

 Time - t

And aquires final velocity - v

The velocity-time graph is a straight line DB.

Initial velocity = OD = u

Final Velocity = OC = v

Acceleration = Slope of line DB,

Acceleration (a)

a = AB / AD 

a = DC / OE 

a = (OC-OD) / OE

a = (v-u) / t

at = v-u

v = u + at

Answer 2

Answer:

v = u + at

Explanation:

we know that acceleration ;a = ∆v/t

a = v-u / t

at = v-u

v = u+at

hope this helps u........
