Question

a body starts from rest and moves with a uniform acceleration of 4 metre per second square until it travels a distance of 800 m .Find the final velocity​

Answer 1

Explanation:

Given

u = 0

a = 4 m/s^2

s = 800 m

v^2 = u^2 + 2as

= 2 ( 4 ) (800)

= 80 m/s

So the final velocity is 80 m/s
