A car starts from rest and accelerates at a steady 6.00 m/s 2. How far does it travel in the first 3.00 s?

Explanation:

Given

car starts from rest i.e. initial velocity is zero

acceleration

Time take

using

where  

x=displacement

u=initial velocity

a=acceleration

t=time

so car travels 27 m in first 3 second

i think the answer is b

so easy. just google the electromagnetic waves and it’ll pop up.
