A brick is projected from ground with speed v at angle `theta` from horizontal. The longer face of brick is parallel to ground. The brick slides along ground through some distance after hitting ground and then stops. The collision is perfectly inelastic. The coefficient of friction is `mu(mu lt cot theta)`. The angle `theta` is chosen such that brick travels the maximum horizontal distance before coming to rest. Find the distance in meters :
