A particle is projected vertically up with velocity `v=sqrt((4gR_e)/3)` from earth surface.The velocity of particle at height equal to half of the maximum height reached by it

A particle is projected from earth surface with a velocity sqrt((4gR)/(3)) in upward direction where R is the radius of earth. Find the velocity of particle when it is at half its maximum height.

A body is projected vertically from the surface of the earth of radius R with velocity equal to half of the escape velocity. The maximum height reached by the body is

A particle is projected vertically upwards from the surface of the earth (radius R_(e) ) with a speed equal to one fourth of escape velocity. What is the maximum height attained by it from the surface of the earth ?

A stone projected vertically up with velocity v from the top of a tower reaches the ground with velocity 2 v The height of the tower
