Astronomers detect a distant meteoroid moving along a straight line that, if extended, would pass at a distance 3RE from the center of the Earth, where RE is the radius of the Earth. What minimum speed must the meteoroid have if the Earth’s gravitation is not to deflect the meteoroid to make it strike the Earth?
