Answer:
v= 12.522 m/s
Explanation:
Supposing we have to find the velocity of the car
By conserving energy we can say that
Initial potential energy= Final potential energy + Final kinetic energy
So
[tex]mgh_{initial}=mgh_{final}+0.5mv^2[/tex]
also h{initial}=18 m
h_{final}=10 m
therefore,
0.5mv^2=mg(18-10)
So
[tex]v=\sqrt{16g}[/tex]
v= 12.522 m/s
