Two bodies 1 and 2 are projected simultaneously with velocities \( v_{1}=2 \mathrm{~ms}^{-1} \) and \( v_{2}=4 \mathrm{~ms}^{-1} \) respectively. The body 1 is projected vertically up from the top of a cliff of height
P \( h=10 \mathrm{~m} \) and the body 2 is projected vertically up from the

W bottom of the cliff. If the bodies meet, find the time (in s) of meeting of the bodies.
