3. An overloaded elevator has a total mass of 1457 kg. Despite of friction force upward with magnitude of 13,000 N and tension, the elevator is moving with constant speed of 13.72 m/s. At the bottom of the shaft is a cushioning spring which is then compressed for 3 m to stop the elevator. Find the force constant of the spring. Please answer correctly, comprehensively, and completely. Because based on experience, some expert answers were wrong. Thank you.
