A boy is standing on a cart moving along `x`-axis with the speed of `10 m//s`. When the cart reaches the origin he throws a stone in the horizontal `x-y` plane, with the speed of `5 m//s` with respect to himself at an angle `theta` with the `x`-axis. It is found that the stone hits a ball lying at rest at a point whose co-ordinates are `(sqrt(3)m, 1m)`. The value of `theta=40^(@)xxC` is (gravitational effect is to be ignored). Find the value of `C`.
