a particle is moving under the influence of an attractive Force mu/y³ towards the axis x. show that if it be projected from the point (0,k) with the component velocities u and v parallel to n axes of x and y,it will not strike the axis of x unless u>v²k² and that in this case the distance of the point of impact from the origin is uk²/√(u-vk)

The International Space Station is orbiting at an altitude of about 3270 km above the earth's surface. The mass of the earth is 5.976 × 1024 kg and the radius of the earth is 6.378 × 106 m.
Assuming a circular orbit, what is the period of the International Space Station's orbit? [T=(2*pi*r)/(GM/r)0.5, r=Re+h, G=6.67*10-11 N*m2/kg2]
