Answer:
The final velocity is [tex]V = 30.25 \frac{m}{s}[/tex]
Step-by-step explanation:
The car starts from rest, this means the initial velocity U = 0.
The time interval is 8 seconds.
The total Distance traveled is 121 meters.
The formula for calculating final velocity(V) is,
[tex](distance) = U(time) + (\frac{1}{2})(acceleration)((time)^{2})[/tex]
[tex]121 = (0)(8) + (\frac{1}{2})(a)(64)[/tex]
a= [tex]\frac{121}{32}[/tex]
The final velocity is given by,
[tex]V = (0) + (a)(time)[/tex]
[tex]V = (\frac{121}{32})(8) = 30.25 \frac{m}{s}[/tex]
