the ans should come out to be
R=(2u<sq (only u)>sin<sq>(a-b)cos<sq>a)/(gcosb)<sq>
the max value will be when a= 45-b/2
where a = angle of projection + angle of inclination(b)
angle of inclination=b
if u ask i will mail u the proof
let it fall on the nth step
v along x=5cos theta
n*8(length of the step)=vcostheta*t
here theta=0(thrown along the x axis)
similarly proceed in y direction and finally equate t in both the eqn
is r the range of the projectile??
however your first question is easily answered. both the bodies will have the same y displacement . so the projectile body will always hit the m2
body
the answer is d . de broglies principle is applicable to each and every object. for eg cars and electron both have wave nature , but becoz of the smaller mass of the electron the wave nature is more prevalent in it.
could you solve this physics problem
an aeroplane is flying in a triangular course of order. the length of each side of the triangle is " a " km and the wind is blowing along its one side with velocity u km/hr . prove that the areoplane will take a*sq.rt of 3(sq.rt of 3 +1)/2u hour to complete...
