A rocket has to be launched from earh in such a way that it never returns. If E is the minimum energy delivered by the rocket launcher what should be the minimum energy that the launcher should have if the same rocket has launcher from the surface of the moon ? Assume that the density of the earth and the moob are equal and that the earth's volume is `64` times the volume of the moon
The escape velocity of a rocket launched from the surface of the earth
The acceleration due to gravity on the moon is (1^(th))/(6) that on the earth. If the earth and the moon are assumed to have the same density, then the radius of the moon is
Why rockets are launched from west to east in the equatorial plane?
Escape velocity from the surface of moon is less than that from the surface of earth because the moon has no atmosphere while earth has a very dense one.
A rocket is launched upward from the earth surface whose velocity time graph shown in figure. Then maximum height attained by the rocket is :-
What is the minimum work that has to be performed to bring a spaceship of mass m=2.0*10^3kg from the surface of the Earth to the Moon?
A rocket is launched vertically from the surface of earth with an initial velocity v . How far above the surface of earth it will go? Neglect the air resistance.
