Acceleration of a car (3583)

Domingo 22 de mayo de 2016, por F_y_Q

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?

Acceleration is defined by:

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

Replace the problem data:

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