Q1Kinematics of Motion in a Straight LineFree sample

A particle $P$ is projected vertically upwards with speed $11\text{ m s}^{-1}$ from a point on horizontal ground. At the same instant a particle $Q$ is released from rest at a point $h\text{ m}$ above the ground. $P$ and $Q$ hit the ground at the same instant, when $Q$ has speed $V\text{ m s}^{-1}$ .

(i)

Find the time after projection at which $P$ hits the ground.

(ii)

Hence find the values of $h$ and $V$ .
