A) travel outside the necleus
Answer:
The compression in the spring is 9.64 meters.
Explanation:
Given that,
Mass of the train, m = 6251 kg
Speed of the train, v = 27 m/s
Spring constant of the spring, k = 48979 N/m
We need to find the compression in the spring when it comes to rest. It is a case of conservation of energy. The kinetic energy of the train is converted to elastic potential energy. So,
x is compression in spring
So, the compression in the spring is 9.64 meters.
Answer:
zero
rank the magnitude of the average velocity over the first 2 second
Answer:
8.33 m/s
Explanation:
v=d/s, velocity = displacement/ time
