A car is increasing its speed from 40 m/s to 70 m/s. What is its acceleration if the time needed was 3 seconds?

P.-S.

Acceleration is defined by:

\color[RGB]{2,112,20}{\bm{a = \frac{v_f - v_i}{t}}}

Replace the problem data:

a = \frac{(70 - 40)\ \frac{m}{s}}{3\ s} = \fbox{\color[RGB]{192,0,0}{\bm{10\ \frac{m}{s^2}}}}
