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...

is the velocity 29.95 at the moment of impact

this means mass has to be variable how are you planning to vary mass

it is definitely same velocity

If same force is needed then it is not possible for any height. At any height Earth's gravitation will be approx. 9.8 and F = mg and mass will remain constant.

is it "the same force or same velocity" at he end of the question

F = ma

concept of impulse is involved

it is 2 sq-cm

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

i calculated pressure = 50000 Area = 2cm^2 force = 50000*(2/10000)=10N but the answer is 20N

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...

You must have seen problems on projectile motion on an incline . What coordinate axis did you choose?

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.
