An elevator mass of 7700 kg falls from a height of 32 m after a sudden failure in the hoisting cable. the mass is stopped by a spring at the bottom of the shaft. determine the spring constant (in kn/m) necessary to bring the elevator and occupants to rest without exceeding an acceleration of 5 g's.

Individuals who live below the poverty line get seriously ill more often than those who do not what could be the hidden variable in this situation?

Ahanging spring stretches by 35.0 cm when an object of mass 450 g is hung on it at rest. in this situation, we define its position as x = 0. the object is pulled down an additional 18.0 cm and released from rest to oscillate without friction. what is its position x at a moment 84.4 s later? express your answer in cm.
