The vertical height between two points A and B is 30 m. A particle
is projected downward from A and at the same time another particle is
projected upward from B with the same speed. Both particles reach the
ground simultaneously. The velocity of the projection of the particle is
(B is on ground)
Show answer and solution
S = 0 = ut -[IMAGE] gt2
[IMAGE] 30 = ut + [IMAGE] gt2 =[IMAGE] by adding
30 = 2ut =[IMAGE] u2 =[IMAGE] ⇒[IMAGE] = u
