Question 3
A particle is let fall from a great height h above the earth. If the acceleration of the particle f=Ax2, where x is the distance of the particle from the centre of the earth, provided xR,R : the radius of the earth, and if f=-g when x=R, show that it reaches the earth with velocity {2gRh(R+h)}12. You may neglect air resistance.
