A projectile of mass 200 g is launched in a viscous medium at an angle

60^{\circ}

with the horizontal, with an initial velocity of

270 \mathrm{~m} / \mathrm{s}

. It experiences a viscous drag force

\vec{F}=-c \vec{v}

where the drag coefficient

c=0.1 \mathrm{~kg} / \mathrm{s}

and

\vec{v}

is the instantaneous velocity of the projectile. The projectile hits a vertical wall after 2 s . Taking

e=2.7

, the horizontal distance of the wall from the point of projection (in m ) is

\underline{\hspace{2cm}}

.
