# Projectile Boat!

A ball is thrown at initial velocity 5 at an angle 15 degree from horizontal and at the same time a boat of velocity 5 at angle 165 degree from the direction opposite to river acceleration is placed in a small river of velocity 0 and acceleration $$g=9.8\text{ m/s}^2$$. Time taken by projectile to fall down is $$t_1$$ and boat to cross river is $$t_2$$. Width of river is $$1.0\text{ m}$$.
