Question

help me!!

Answer 1

particle "A" was projected vertically upward from point a with an initial velocity of "u" m/s when time = 0 and after "t" seconds particle "B" was projected vertically upward with an initial velocity of "2u". Draw a velocity time graph to represent the motion of "A" in relative to "B" . hence deduce that the time that will take by both particles to collide is
\[\frac{ t(4u + 91) }{ 2(u + g t) }\]

Answer 2

Help me with the graph pls.... @ganeshie8 , @mathstudent55 @phi , @Yahoo!
