Answer:

14.8 m

Explanation:

S= ut + [tex]\frac{1}{2}[/tex]a[tex]t^{2}[/tex]

where u = initial velocity

S= (0 [tex]\frac{m}{s}[/tex])(2[tex]s[/tex]) + [tex]\frac{1}{2}[/tex](7.4[tex]\frac{m}{s^{2} }[/tex])(2[tex]s^{2}[/tex])

S=  [tex]\frac{1}{2}[/tex](7.4[tex]\frac{m}{s^{2} }[/tex])(2[tex]s^{2}[/tex])

S=14.8 m
