DYNAMICS $($MECHANICAL ENGINEERING$)$

Figure Q$1$ shows a motorcy clist performing a ramp jump show. The height of the ramp, $h$ is $2\mathrm{.}5$ m from the ground. The motorcycle is projected through an angle $=60$ at point $O.$ Knowing that the motorcycle lands at point $B$ where the distance is $D=20m.$ Determine,

a$)$ the initial speed, $V_0$ of the motorcycle at point $O,$ and

b$)$ the maximum elevation from the ground reached by the motorcycle.

PLEASE REFER TO THE FIGURE GIVEN AND PLEASE DRAW THE FREE BODY DIAGRAM AND LABEL IT $)$THANKS$.$
