When in orbit, astronauts experience weightlessness. what is this caused by?
the astronauts experience no contact (normal) forces with their surroundings.
the astronauts have no mass in space.
gravitational forces do not occur in space.
astronauts are too far away from the earth to feel its gravitational pull.

answer:

c. gravitational forces do not occur in space

explanation:

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
