suppose that we have following problem suppose that ball is dropped from upper observation deck of the CN tower,450 meter from the ground,and distance h is given in 1 second interval
Time Height
0 450
1 445
2 431
3 408
4 375
5 372
6 279
7 216
8 143
9 61
this is problem taken from calculus book,as graph was given it was clear that linear model was not suitable,so author choosed quadratic model i have tried to get the same result as author had which is expressed like this
h=449.36+0.96*t-4.90*t^2
but when i have wrote quadratic form y=a*x^2+b*x+c and put first three x values,got y=-4.5*x^2+0.5*x+450 i am interested how accurate and correct it is?
