Question

an object start from rest with uniform acceleration and 100m in 10s Find the speed of the object just after covering 50m
fastly please ......​

Answer 1

Explanation:

initial velocity (u) = 0

use equation of motion

s = ut + at²/2

100 = 0*10 + a*10*10/2

a = 2 m/s²

now,

v² = u² + 2as

v² = 0 + 2*2*50

v = 10*√2

v = 14.14 m/s
