This state of motionlessness occurs because all of the kinetic energy in the car is absorbed by the spring in the form of elastic potential energy. The mathematical representation is:
1/2 mv² = 1/2 kx²
25m = kx², where m is the mass of the cart, k is the spring constant and x is the spring's extension.
They has been very successful but they are very expensive to operate that is your answer I hope this helps
Answer:
They decrease trauma by allowing for a more gradual change in velocity
Explanation:
There water has a lot of salt in it, so it would be denser. People float better when the water is denser.
