Could you please tell me the gravitational pull for Windsor Ont. or how to find it. My phisics teacher has told me that 9.8m/sec./sec. will not do.

If you could answer this question I would be very thankful.

According to European standards: g=9,7803*{1+0,0053*[sin (fi)]^2}-3e(-6)*z ; [m^2*s^(-1)].

Where: fi- latitude in degrees; z-metres above sea level

Hope it will help You
