H=-16t^2+49
find where h=0
0=49-16t^2
0=7^2-(4t)^2
difference of 2 perfect square
0=(7-4t)(7+4t)
set to zero
7-4t=0
7=4t
7/4=t
7+4t=0
4t=-7
t=-7/4
faslse, this is before the person jumps
answer is 7/4 seconds
A = V1 - V0/t.....multiply both sides by t
At = V1 - V0....add V0 to both sides
At + V0 = V1
