Question 1033814
t=======h
0=======0, substitute 0 in for t
0.2=====-4.9(0.04)+22.7(0.2)=4.344; the 0.04 is 0.2^2.
0.4=====-4.9*(0.4)^2+22.7(0.4)=8.296
Just continue along these lines. Be sure you watch for the negative sign in front of the first term and square the value before multiplying by -4.9.
Calculator can do this with lists, and a spreadsheet can do this by writing 
=[-4.9(x)^2+(22.7)*x] and making a column with x=0,0.2,0.4.
