Question

please help easy question

Answer 1

a) recall, The average velocity is a displacement divided by a time, or in this case since velocity vs time is shown and there is a constant acceleration(straight line), the average velocity can be found from
\[\large v _{ave }=\frac{ v _{1}+v _{2} }{ 2 }\]

Answer 2

from t=0 to t=4 seconds
\[\huge v _{ave}=\frac{ v _{t=0} +v _{t=4}}{ 2 }\]

Answer 3

6m/s??
