Question

dimentionally prove that s=ut+1/2at2

Answer 1

Answer:

average velocity = u+v/2

also , distance travelled

s = average velocity * time

s = u+v/2 * t

s = u+u+at *t/2

[ v=u + at ]

s = 2u +2 at * t/2

s = 2ut + 2at^2/2

s = ut + 1/2at^2

hope it helps you

Answer 2

Step-by-step explanation:

Displacement=(v-u/2)t

s. =(u+at+u)t

2

=(2u+at)t

2

=(2u+1at)t

2. 2

s=ut + 1 at²

2

• Hence proved
