Notes: Move “C” to the other side and create “space” for your new numbers.Create ( )2 for you perfect squareFind the number to be added to both sides and fill in your spaces.Make your equation look like y = ( )2 + c. This will create “Vertex Form” which will be used in MT6 for graphing.

Notes: Assign your values to your variablesH is ending heightT is timeV is velocityC is starting height(when you are on the ground, height is 0)
0 (the ground)
10 seconds
? I have no idea
0 (the ground)

Notes: Use gravity formula - h = -16t2 + vt + c, plug in variables, and solve for “V”
0 = -16(10)2 + v(10) + 0
H=0T=10V=?C=0
0 = -1600 + 10v
1600 = 10v
V=160
160h = -16(t)2 + v(t) + c

Notes: Draw a picture of what is happening. You know velocity (160), you must figure out how many second it took to get to the maximum height. Plug in and solve.
T=0 T=10
T=?(Maximum height)

h = -16(5)2 + 160(5) + 0
h = -400 + 800
H=400
