A small block of super dense material has a mass equal to the half of the mass of the earth . It is released from the height `H(H lt lt ` radius of the earth) . Find its speed when its height from the eath surface decreases by `75%`.

A small block of superdennse material has a mass of 3xx10^24 kg. It is situated at a height h (much smaller than the earth's radius) from where it falls on the earth's surface. Find its speed when its height from the earth's surface has reduced to h/2 . The mass of the earth is 6xx10^24kg

A small body of super dense material, whose mass is half the mass of the earth (but whose size is very small compared to the size of the earth), starts from rest at a height H above the earth’s surface, and reaches the earth’s surface in time t. Calculate time t assuming that H is very small compared to the radius of the earth. Acceleration due to gravity near the surface of the earth is g.
