A particle is dropped from height 100m and another particle is projected vertically upward with velocity 50m/s from the ground along the same line.find out the position where two particle will meet

Question

Ram agrawal · Answer

I'm doing this ques with the concept of relative motion Let us consider dropped particle A and upward thrown particle B.(suppose u are a insect and sitting on B , now B will be at rest for u)

Ram agrawal · Answer

Now , V ab = V a -V b (velocity of A w.r.t B) (while sitting on A seeing B is V ab ) V ab = 0-50 = -50m/s a ab = -g-(-g) =0 ( acceleration of A w.r.t B) Distance=100m (as time and distance between 2 particle are independent of frame) Now , since a = 0 it is a simple non-accelerated motion. Applying , Speed=distance/time 50=100/t =>time=2 sec Now, we can calculate distance travelled by A in time=2sec , that is at which height they will meet.) =>S=ut+at 2 /2 ( 2 nd equation of motion) =>S=(0)(2)-(10)(2) 2 /2 =>S=-20m ( negative sign signifies direction) So, the particles will meet 20m from top or 30m above ground. Here is ur requested answer, there is also a suggestion if u understood just do it without seeing above
