(3.0)(0.612)+1/2(-9.81)(0.612^2)

This DOES NOT equal  0.459

 

3.0*0.612   +    1/2*-9.81*0.612^2

 

                  0.612^2 = 0.374544

 

=3.0*0.612   +    1/2*-9.81*0.374544

 

                 3.0*0.612 = 1.836

                  1/2=0.5

 

=   1.836   +    0.5*-9.81*0.374544  

=   1.836   +    -0.5*9.81*0.374544  

=   1.836   -    1.83713832

 = -0.00113832

 

check

(3.0)(0.612)+1/2(-9.81)(0.612^2) = -0.00113832
