An object is dropped from rest from a height 7 × 10^6 m above the surface of the earth. If there is no air resistance, what is its speed when it strikes the earth? The acceleration of gravity is 9.81 m/s2 and the radius of the Earth is 6.37 × 10^6 m. Answer in units of km/s.
Please explain how to solve for these
