Since acceleration is constant
So the distance moved in constant acceleration will be given as
[tex]d = \frac{v_f + v_i}{2} t[/tex]
as we know that
[tex]v_f = 20 m/s[/tex]
[tex]v_i = 0[/tex]
t = 17 s
so distance moved is given by
[tex]d = \frac{0 + 20}{2}(17)[/tex]
[tex]d = 170 m[/tex]
so distance moved will be 170 m
