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...
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
0.5dv^2 = p
