Answer:
90 N
Explanation:
The force applied to the ball is given by:

where
is the change in momentum of the ball
is the time taken
The change on momentum of the ball is:

So, the force applied is

F= ma
F= (600/-10) -10
F= 580n
At least I think that’s the answer
I believe that since Kepler focused his studies the rotation of the planets, and the stars, that he is the one who developed the law, which is called the first law of planetary motion.
I would say a because i just had this
Answer;
= 4.49 g/cm³
Explanation;
Density = Mass / Volume
mass = 1.41 kg,
volume = 0.314 L
but; 1 kg = 1000 g and 1 L = 1000 mL
Thus;
Density = 1.41 kg/0.314L
Density = 4.49 kg/L (1000g/ 1kg)(1L/1000cm^3)
Density = 4.49 g/cm^3
