A ball is thrown from the bottom of a rectangular pit with a speed v0=20 m/s at an angle a=60° to the horizon. The depth of the pit is h=10 m, the distance from the throwing point to the wall of the pit is l=10 m. The acceleration of free fall can be taken as g=10 m/s2. Will the ball fly out of the hole?
