thread ur question again so that more learned people can go through it and try to elucidate the situation a bit more it is getting complicated That is all i can offer
according to me the initial weight of object should be varied mathematically with a function
so that by the time it reaches ground its weight becomes 203.66 N from 68 N now we have height as a variable and some mathematical function you wish to use, final velocity of the object. try to write...
If same force is needed then it is not possible for any height. At any height earths gravitation will be approx. 9.8 and F = mg and mass will remain constant.
no the data is correct i think "with water splashing out parallel to plate" is the key point to he problem and this is where i make a mistake while applying Bernoulli
any clue
Homework Statement
A jet of water having velocity v = 10m/s and stream cross section = 2cm^2 hits a flat plate perpendicularly, with water splashing out parallel to plate. Find the force that plate experiences.
density of water d=1000kg/m^3
Homework Equations
0.5dv^2 = p
The Attempt...
otherwise angle should be given. Always take coordinate axis in such a way that variables in question are reduced this is the concept to minimize the time you take for problem solving.
