I was set this question and have no clue how to solve it...(adsbygoogle = window.adsbygoogle || []).push({});

A 1100 kg car racing up a mountain road runs out of gas at a height of 36 m while traveling at 16 m/s. Cleverly, the driver shifts into neutral and coasts onward. Not having any brakes, at what speed will the car reach the bottom of the hill?

I found mgh of the car as 1100 x 9.81 x 36 and then equated this to 1/2mv2 to try and find velocity and I got 26.5m/s but this is wrong...any help? Thanks
