Answer :
- Time=6s
- Vertex height's time= 6/2=3s
- Acceleration due to gravity=10m/s^2
Apply second equation of kinematics
[tex]\\ \rm\hookrightarrow s=ut+\dfrac{1}{2}gt^2[/tex]
[tex]\\ \rm\hookrightarrow s=1/2(10)(3)^2[/tex]
[tex]\\ \rm\hookrightarrow s=5(9)[/tex]
[tex]\\ \rm\hookrightarrow s=45m[/tex]
It rises 45m
