Answer:
The final speed of the vehicle is 36 m/s
Explanation:
Uniform Acceleration
When an object changes its velocity at the same rate, the acceleration is constant.
The relation between the initial and final speeds is:
[tex]v_f=v_o+a.t[/tex]
Where:
vf = Final speed
vo = Initial speed
a = Constant acceleration
t = Elapsed time
The vehicle starts from rest (vo=0) and accelerates at a=4.5 m/s2 for t=8 seconds. The final speed is:
[tex]v_f=0+4.5*8[/tex]
[tex]v_f=36\ m/s[/tex]
The final speed of the vehicle is 36 m/s
