A Particle is projected upwards from ground with a speed u at an angle theta with the horizontal. At the same time another paricle is dropped from a height h if they collide at a horizontal distance s from the point of projection then h is?

Best ResponseYou've already chosen the best response.0At the moment of collision t = s/v1x , where v1x  initial horizontal component of velocity of the first object for the second object y(t) = h  gt^2/2 = h  gs^2/(2 u^2(cos theta)^2), but this is true only if the collision occurs before the first object rises its maximum height.

Best ResponseYou've already chosen the best response.0Sorry I got little confused.That's all ok, we are not considering vertical motion of the first object, so the resultant equation is true for every moment of time. At the moment of collision t = s/v1x , where v1x  initial horizontal component of velocity of the first object v1x = u cos theta for the second object y(t) = h  gt^2/2 = h  gs^2/(2 u^2(cos theta)^2)

Best ResponseYou've already chosen the best response.0The last equation is the answer y(t) = h  gs^2/(2 u^2(cos theta)^2) where y  is the height at which the second object is located h  is the initial height of it

Best ResponseYou've already chosen the best response.0i'm replacing theta with O v cosO is horizontal component of initial velocity of particle 'a'.. which will remain unaltered as no force thus acceleration acts on it (the horizontal component) hence, by eq, s= ut +1/2 at^2 a=0 u=u cosO so s= u cosO t
