Answer:
The momentum is 1.94 kg m/s.
Explanation:
To solve this problem we equate the potential energy of the spring with the kinetic energy of the ball.
The potential energy 
of the compressed spring is given by
,
where 
is the length of compression and 
is the spring constant.
And the kinetic energy of the ball is
When the spring is released all of the potential energy of the spring goes into the kinetic energy of the ball; therefore,
solving for 
we get:
And since momentum of the ball is 
,
Putting in numbers we get:
Answer:
correct answer is D

When towing a skier with a personal water craft with an
observer on board, the people in the personal water craft must only carry three
to five people for there is only a limited space of people to be carried on
board for it could cause conflict on board when there a lot of people of board.
