Answer:
100 newton
Explanation:
newton third law of motion says to every action there is an always an equal and opposite reaction so the magnitude will stay equal but opposite direction
Answer:
I would say the answer is A... but I'm not so sure ....
Answer:
The time taken to stop the box equals 1.33 seconds.
Explanation:
Since frictional force always acts opposite to the motion of the box we can find the acceleration that the force produces using newton's second law of motion as shown below:

Given mass of box = 5.0 kg
Frictional force = 30 N
thus

Now to find the time that the box requires to stop can be calculated by first equation of kinematics
The box will stop when it's final velocity becomes zero

Here acceleration is taken as negative since it opposes the motion of the box since frictional force always opposes motion.
Answer:
ρ = M / V = 2 g / .5 cm^3 = 4 g/cm^3
