Hello @Wpisd3039,
How are you doing? In this case,
The ball will strike the ground when h=0.-16t²+272t+1344=0t₁,₂=(-272+-√(272²+4*16*1344))/2*(-16)t₁,₂=(-272+-400)/(-32)t₁=(-272+400)/(-32)=-4 or t₂=(-272-400)/(-32)=21Time cannot be negative value so t₂ is solution. The ball will strike the ground in 21 seconds.
I hope I helped, Contact me if you need more assistance.
Thank you,
