SUMMARY
The discussion centers on calculating the tension in the cable of an elevator weighing 1400 kg, which is initially moving downward at 12 m/s and comes to a stop over a distance of 41 m. The acceleration of the elevator is determined to be 1.75 m/s² using the kinematic equation v² = v₀² + 2aΔx. The final calculation for the tension in the cable, using the formula T = m(a + g), results in a value of 16170 N, where g is the acceleration due to gravity (9.81 m/s²).
