Answer:19.32 m/s
Explanation:
Given
initial speed of car(u)=4.92 m/s
acceleration(a)=![3.2 m/s^2](https://tex.z-dn.net/?f=3.2%20m%2Fs%5E2)
Speed of car after 4.5 s
using equation of motion
v=u+at
![v=4.92+3.2\times 4.5=4.92+14.4](https://tex.z-dn.net/?f=v%3D4.92%2B3.2%5Ctimes%204.5%3D4.92%2B14.4)
v=19.32 m/s
Displacement of the car after 4.5 s
![v^2-u^2=2as](https://tex.z-dn.net/?f=v%5E2-u%5E2%3D2as)
![19.32^2-4.92^2=2\times 3.2\times s](https://tex.z-dn.net/?f=19.32%5E2-4.92%5E2%3D2%5Ctimes%203.2%5Ctimes%20s)
![349.05=2\times 3.2\times s](https://tex.z-dn.net/?f=349.05%3D2%5Ctimes%203.2%5Ctimes%20s)
s=54.54 m
