Question

using the concept of distance time graph derive the relation v-u+at​

Answer 1

Answer:

Let an object is moving with uniform acceleration.

u = initial velocity of object

v = final velocity of object

a = uniform acceleration

Let object reaches at point B after time (t) Now, from the graph

Slope = Acceleration (a)=

time

change in velocity

Change in velocity = AB = v - u

Time = AD = t

a=

t

v−u

Solving we get

v=u+at.........(1
