Question

A body starts from rest and accelerates by 9 m/s2. Find velocity and distance covered by the body after 2seconds.

please tell the answer with the solving.​

Answer 1

Explanation:

u=0

a=9m/s²

t=2sec

since we know that

v = u+at

v = 0+ 9×2

v = 18m/s

By Third law of Motion

s = ut +1/2at²

s = 0×2 + 1/2 ×9 ×(2)²

s = 1/2×9×4

s = 18m
