we can use height formula 

where 
h(t) is the height after t seconds
v is velocity 
h(0) is initial height 
g is acceleration due to gravity 
we know that 
g=32 ft/s^2
we have 
v=18.5ft/s
h(0)=4.5ft
so, we can plug these values
and we get 


now, we have to find time when object will hit the ground 
and we know that object will hit the ground when height becomes 0
so, we can set h(t)=0
and then we can solve for t

we can use pythagoras theorem
