A man is riding on a flat car travelling with a constant speed of `10m//s`.He wishes to throw a ball through a stationary hoop `15 m` above the height of his hands in such a manner that the ball will move horizontally as it passes through the hoop. He throws the ball with a speed of `12.5 m//s` w.r.t himself.
At what horizontal distance in front of the hoop must he release the ball?

You can attempt the problem in a reference frame fixed to the car or in the reference frame fixed to the ground. Fundamentally, these two reference frames are equivalent in all respects, but in the reference frame fixed to the car, the calculations are slightly easier.
