Question: help = . Two particles P and Q have mass 1 kg and 2 kg respectively. They are projected along a vertical line with velocity

help help = . Two particles P and Q have mass 1 kg

= . Two particles P and Q have mass 1 kg and 2 kg respectively. They are projected along a vertical line with velocity up = 20 m/s and ug = 5 m/s when separation between them QO was 60 m. P was projected u vertically up while Q was projected vertically down. Calculate the maximum height 60 m attained by the centre of mass of the system of two particles, measured from the initial P position of P. Assume that the particles do not collide and that the ground is far below their point of projection (g = 10 m/s?) fur =
