    Falling egg question (with energy equations)

    oh ok, does that mean that the kinetic energy will be the same as the loss of potential energy then? But still, how do i work out the speed and momentum?

    Falling egg question (with energy equations)

    An egg of mass 5.8*10^-2 is dropped from a height of 1.5m onto a floor. Assuming air resistance is negligable, calculate for the egg: a) loss of potential energy. b) the kinetic energy just before impact. c) the speed just before impact d) the momentum just before impact. So far i have...

    How to Calculate Wind Pressure on a Wall?

    That is the exact question that i have written, but i presume it means the force that the wind is pushing at the wall with.

    How to Calculate Wind Pressure on a Wall?

    The wind in a severe storm is blowing 30 ms perpendicularly to the wall of a large barn of area 80 m2. Calculate the pressure exerted on it, assuming that the air density is 1.3 kg m3. I am quite new to this unit so i really have no idea what to do. Any help apreciated!
