Yes, skis WILL help you get downhill faster if there is snow. You need to know how steep the hill is to know how fast you will go. If you add some ski wax to the bottom of your skis, you will go extra fast.
Skis are smooth at the bottom, and snow will be soft ( or hard ). That will create less friction between your skis and the snow. If you don't know what friction is, it's the force when something is moving on a surface. Skiing downhill will show you a perfect example of it.
over 100mph at least
Skiers use flat skis to to help them go fast they make a pizza by digging the side of their skis
I would say that a ski can easily reach 40-50 mph if one's advanced enough and using long skis and going straight down paralel. Demensions? My skis are for moderate skill levels and they are 151 cm, but racing skis can get up to 210 cm. Width depends on the brand. Probably about 4 inches.
we could go about 35mph when not going downhill you can go 28mph
Skiers use flat skis to to help them go fast they make a pizza by digging the side of their skis into the snow the side of the skis are sharp so that's makes them stop and go
No, the ski format is used with skins to climb up mountains, not for going downhill. You go downhill in board format. Then back up again in skins with ski format.
you bend down, don't turn, keep skis straight, and you do better the more weight you have
It depends on the model. Most unmodified jet skis have a top speed between 45 and 70 miles per hour.
Boatercycles (Jetskis) can be fast, depending on how immensely fat the person is, and depending on how much water there is and how fast the engine is designed to go
Whatever speed they're allowed by the driver of the vehicle.
At about 180 mph if you fall out of an aeroplane with no parachute.
50-55 MPH
