Question #155945

What is the acceleration of a car (km/hr²) that goes from 40 km/hr to 80 km/hr in 0.3 hrs

Expert's answer

By the definition of acceleration, we have:

a=\dfrac{v-v_0}{t},

a=\dfrac{80\ \dfrac{km}{hr}-40\ \dfrac{km}{hr}}{0.3\ hr}=133.3\ \dfrac{km}{hr^2}.

Answer:

$a=133.3\ \dfrac{km}{hr^2}.$
