Answer:
average acceleration = 6 [tex]\frac{m}{s^2}[/tex]
Explanation:
Recall that the average acceleration [tex](a)[/tex] is defined by the change in velocity from an initial velocity [tex](v_i)[/tex], to a final velocity [tex](v_f)[/tex] over the time (t) it took that change to happen. Then, in mathematical terms this is:
[tex]a=\frac{v_f-v_i}{t}[/tex]
with our information this becomes:
[tex]a=\frac{v_f-v_i}{t} = \frac{100-40}{10}=6\,\frac{m}{s^2}[/tex]
