Jet Ski Floats

Jet Ski Floats
Does anyone know a website that shows how much force a person hitting the water at 30 mph experiences ...?

Me and some friends were held yesterday in the river and entered a float. He was dragged by a jet ski. The float that turns sometimes, and the jet ski might be doing 30 to 40 mph ... and fell into the water and cover. Nice raw impact! Sometimes, Jet Ski would go in a circle about 10 mph, but the external force on the float was difficult to endure without being thrown to the side when they were finally thrown into the impact was so hard it seemed. Does anyone know any website that compares perhaps falling off a building to hitting the water and a certain mph, or maybe a graphic. Thank you. I wish there was something that said that, if a guy 185 pounds hit the water at 35 mph is = a fall from a 10-story building,

It is basically impulse momentum. The determinants that effect by force a person hitting the water are the speed at which touched water, the length of time it takes the person to slow from a stop, and the mass of the person. The formula is m * Δv = F * F Dt = m * Δv / Dt So if you are going 30 mph to 0 mph, Δv = (30 - 0) = 30, the average person is 4.11 slugs (about 132 pounds) The only thing we lack is Dt From experience, I guess Dt = 1 s, or something similar. If you find any sources that say otherwise, try that .... so F = m * Δv / Dt F = 4.11 * 30 mph / 1 s = 181 pounds or about 804 N This is roughly the equivalent of an adult man sitting in you, nothing too dangerous. If Dt were smaller, the force increase. That's why I always say not the fall that kills you, it's the sudden stop in the final.

they 2 fell aff n the ski floats away headin fir a yaught. dodgy lol
