Answer:
p to the left
Explanation:
According to law of conservation of momentum "total momentum of an isolated system remains constant".
we consider astronaut and astronaut drill as an isolated system. If the drill gain momentum p to the right so in order for momentum to remain constant the astronaut will gain the same momentum but in opposite direction i.e momentum p to the left.
Initial momentum = 0 ( before she throw astronaut belt)
Final momentum = p - p = 0 (After she throw astronaut belt)
Hence momentum of the system remains constant i.e zero.

Answer: C. gravitational kinetic
Explanation: Gravitational potential energy is the energy calculated from an object's mass height and the acceleration due to gravity. The gravitational potential energy is the energy an object has as a result of the position of the object in a gravitational field.
Answer:
4. All of the above
Explanation:
The purpose of striking the ball in a volleyball game:
From the serve you could state that you need to place the ball in motion.
When returning a shot of, you normally want to change the direction of the ball's motion.
During a dropshot, you purposely want to slow down the ball's motion.
The correct answer must be all of the above.
