On the way to the moon, the Apollo astro- nauts reach a point where the Moon's gravi-
tational pull is stronger than that of Earth's.
Find the distance of this point from the
center of the Earth. The masses of the
Earth and the Moon are 5.98 x 1024 kg and
7.36 x 1022 kg, respectively, and the distance
from the Earth to the Moon is 3.84 x 108 m.

What would the acceleration of the as-
tronaut be due to the Earth's gravity at
this point if the moon was not there? The
value of the universal gravitational constant
is 6.672 x 10-11 N. m?
· m²/kg?
Answer in units of m/s?.
Answer in units of m/s2

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
