Imagine that two tunnels are bored completely through the Earth, passing through the center. Tunnel 1 along the Earth’s axis of rotation, and tunnel 2 is in the equatorial plane, with both ends at the Equator. Two identical balls, each with a mass of 5.00 kg, are simultaneously dropped into both tunnels. Neglect air resistance and friction from the tunnel walls. Do the balls reach the center of the Earth (point C) at the same time? If not, which ball reaches the center of the Earth first?
