Answer:
x2=0.732m
Explanation:
We can calculate the spring constant using the equilibrium equation of the block m1. Since the spring is in equilibrium, we can say that the acceleration of the block is equal to zero. So, its equilibrium equation is:
Then using the equilibrium equation of the block m2, we have:
In words, the lenght x2 of the spring when the m2 block is hung from it, is 0.732m.
If the net force acting on a moving object causes no change in its velocity, the object's momentum will stay the same.
<h3>What is momentum?</h3>
Momentum of a body in motion refers to the tendency of a body to maintain its inertial motion.
The momentum is the product of its mass and velocity.
This suggests that if the net force acting on a moving object causes no change in its velocity, the momentum of the object will remain the same.
Therefore, if the net force acting on a moving object causes no change in its velocity, the object's momentum will stay the same.

Height and altitude have the same meaning.
Because 1 km = 10³ m, the altitude is
(4301 m)*(10⁻³ km/m) = 4.301 km
Answer: 4.301 km
