Sergio Ramos, under the pressure he felt in his boots, made wrong parameter calculations for his penalty and the ball of mass m is struck from the ground on angle 45 degrees to the horizontal and with velocity equal to the half of the cosmic velocity. The ball did not go into the opposing goal. Knowing the radius and mass of Earth, Rt and M respectively, and assuming spin of the Earth and air resistance are negligible:

a) Calculate the ball movement constants.
b) If the International Space Station is located in the orbit of radius 3Rt, should its inhabitants be alert of the ball striking their station
