An asteroid is moving directly towards the
centre of the earth. When at a distance of
10R (R is the radius of the earth) from the earths
centre, it has a speed of 12 km/s. Neglecting
the effect of earths atmosphere, what will be the
speed of the asteroid when it hits the surface
of the earth (escape velocity from the earth is
11.2 km/s) ? Give your answer to the nearest
integer in kilometer/s _____.
