A smooth slide $AB$ is fixed so that its highest point $A$ is $3{\text{ }}m$ above horizontal ground. $B$ is $h{\text{ }}m$ above the ground. A particle $P$ of mass $0.2{\text{ }}kg$ is released from rest at a point on the slide. The particle moves down the slide and, after passing $B$, continues moving until it hits the ground (see diagram).
The speed of $P$ at $B$ is ${v_B}$ and the speed at which $P$ hits the ground is ${v_G}$.
a) In the case that…
