A projectile of mass 200 g is launched in a viscous medium at an angle 60∘ with the horizontal, with an initial velocity of 270m∕s. It experiences a viscous drag force

where the drag coefficient c=0.1kg∕s and

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
