Ответ:
boy throws the ball with speed 20 m/s at an angle 40 degree
so the components are given as
now the time taken by the ball to drop down by 5 m is given as
now by solving above quadratic equation we have
now in the same time the distance traveled horizontally is given as
so it will cover 5.3 m horizontally while it is dropped down by distance 5 m and it will take 0.345 s for the whole.
