A bullet fired vertically upwards from a gun held 2m above the ground reaches its maximum height in 4sec, calculate its initial velocity and the total distance the bullet travels by the time it hits the ground

At the pinnacle, Vv=0
Vv=Viv+ gt
0=ViV-9.8*4 solve for initial velocity.

total distance?
H(4)=H(o)+Viv*4-9.8(4^2) solve for H(4)

total distance: 2*H(4)+2
