Transcript of real life quadratic

Motion formula H(t)=0
V=0
h=14
g=32
t=
s s
t H(t)=-1/2gt²+vt+h H(t)= Ending Hieght
V= Volacity
g= Gravity
t= Time
h= Starting Hieght

Gravity can be two numbers depending on weather its meters or feet.
g=meters= 9.8 mps
g=feet= 32 fps Real-Life Quadratic Project
by Robin James H(t)=-1/2gt²+vt+h
0=-1/2(32)t²+(0)t+14
0=-16t²+14
a=-16 b=0 c=14
0±√0-4(-16)(14)
—————————— =

t=30/-32 or t=-30/-32
t= 30/32
t≈ -1 or t≈ 1
