TRUE or FALSE
1. A spacecraft must attain a speed of 11.2 km/s to leave the Earth's surface.
2. It is easier to leave the surface of Jupiter than Earth.
3. Escape velocity is affected by the planet's mass.
4. Mars has smaller escape velocity than Venus and Earth because it is farther
from the sun.
5. The escape velocity of a planet is not affected by the sun's warping of space-
time.
