Hello everyone!!

This is a famous question may be someone here familiar with it:

Sergio Ramos, panicked by the responsibility at his feet, miscalculates the parameters of a penalty and the ball, a mass of M, in launched at an angle Pi/4 with the vertical and with a speed equal to half the fired shot’s velocity, but the ball never reached the opposite goal.

Assuming we know the radius and mass of the Earth, Rt and M respectively, and neglect the rotation of the earth and air friction:

1-Calculate the constants of motion of the ball.

2-If the international space station has a circular orbit of radius 3RT, should the occupants have feared a possible impact from the ball?
