and a density of 470 kg/m 3 . What is the area

of the slab if it floats just awash (top of slab

is even with the water surface) in fresh water

when a 65.7 kg swimmer is aboard? Answer

in units of m 2 .

im trying to use pressure=density of water times thickness of slab times 9.8 and mass=density of water times thickness of slab times area

i think I am on the correct path here but I am sure as how to account for the force of the person on the slab in these equations

A tall water cooler tank is standing on the

floor. Some fool punched two small holes

in the tank's wall, one hole at a height of

34 cm above the floor and the other hole

60 cm directly above the first hole and 94 cm

above the floor. Each hole produces a jet of

water that emerges in a horizontal direction

but eventually hits the floor at some distance

from the tank.

If the two water jets (emerging from each

hole) hit the floor at exactly the same spot,

how high H is the water level in the tank

(relative to the room's floor)? Answer in

units of cm.

i can't even find the correct equations to use for this problem, can anyone offer some help
