Question

A little girl kicks a soccer ball. It goes 10 feet and comes back to her. How is this possible? 

Answer 1

Heya user,

Consider the projectile [ tilted at π/2 ] with directrix --> y = x²

or simply, consider a half-ellipse --> y = x²;

The girl hits the ball, and due to some obstruction, or repression, the reacting force causes the ball to come back to her...

In case the projectile is upward ---> the ball is experiencing gravity

Answer 2

Maybe she kicked it upwards. It came back to her because of gravity. It is totally possible, After all direction is not mentioned in the question.

Hope it helps mate...
