The radius and mass of the Earth are 6.4 $\times$ 10⁶ m and 5.98 $\times$ 10²⁴ kg. Assume that a meteor starts at infinity with zero velocity and is attracted to the Earth. Neglecting friction, the speed at which it will strike the Earth is

Question

Quizplus · Accepted Answer

The speed of the meteor can be determined using the formula for escape velocity, which is independent of the mass of the object. The escape velocity from Earth is approximately 11 km/s, which is equivalent to 11,000 km/h.
