Question

While traveling along a highway, a driver slows from 24 m/s to 15m/s in 12 seconds. What is the automobiles acceleration?

Answer 1

a = -0.75 m/s2

Step-by-step explanation:

a = acceleration

v = final velocity

u = initial velocity

t = time

a = (v-u)/t

a = (15-24)/12

a = (-9)/12

a = -3/4

a = -0.75 m/s2
