In general, a rocket that rises from Earth but never attains escape velocity will follow a parabolic trajectory. This means that it will initially travel upward, but its velocity will gradually decrease as it climbs. Eventually, the rocket will reach a point where its velocity is zero and it will begin to fall back to Earth.
The distance that a rocket travels before falling back to Earth will depend on its initial velocity. A rocket with a higher initial velocity will travel further before falling back than a rocket with a lower initial velocity.
The angle of ascent of a rocket will also affect its trajectory. A rocket that is launched at a shallow angle will fall back to Earth sooner than a rocket that is launched at a steeper angle.
Finally, the distance that a rocket travels before running out of fuel will also affect its trajectory. A rocket that runs out of fuel sooner will fall back to Earth sooner than a rocket that has more fuel.
In conclusion, a rocket that rises from Earth but never attains escape velocity will eventually fall back to Earth due to the pull of gravity. The exact trajectory of the rocket will depend on a number of factors, such as its initial velocity, angle of ascent, and the distance it travels before running out of fuel.
