How long will it take a car to speed up from 2m/s to 34m/s if it can accelerate 8m/s/s in the direction it is moving?

Initial velocity (U) = 2m/s

Final velocity (V) = 34m/s

Acceleration (a) = 8m/s²

Then

time(t) = v - u

                a

= (34 - 2) /8

= 32/8

= 4s

Explanation:

gravity causes stares to cluster i think so

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
