If you neglect friction and air resistance what is the bobsled's speed at the bottom of the hill?

Based on the information given it's hard to say.
Two factors to be taken into consideration:
(1) The effect of acceleration (9∙81 m/s) due to gravity.
(2) The slope of the track.

Not enough information is given, you need the angle of the hill to determin how much gravity is pulling the sled down the hill versus how much is keeping on earth. The sled will go a lot faster on a 45 deg. downslop then a 5 deg.

1/2*T*10T=164
5T^2=164
T^2=32.8
T=5.72
5.72*10=57.2m/s
