Question

Acellus

A car accelerates for 12.0
seconds at a rate of 1.20 m/s2. If
the final velocity is 30.0 m/s, what
was its starting velocity?

Answer 1

Vi=15.6m/s

Step-by-step explanation:

a=(Vf-Vi)/t

when we find Vi from the above formula

Vi = Vf - at

Vi=30m/s - 12sec×1.2m/s^2

Vi = 15.6m/s
