Question

A car starts from rest and reaches a speed of 14 m/s in 10s. Its acceleration is what/

Answer 1

Vi = initial velocity = 0 m/s (rest)

Vf= final velocity = 14 m/s

t = time = 10 seconds

a = acceleration

a = (vf - vi ) / t

Replacing:

a = (14 m/s - 0 m/s ) / 10 s = 14 m/s / 10 s= 1.4 m/s^2

acceleration = 1.4 m/s^2
