| Determine the force of pressure of passengers on the floor of the elevator car, if their mass is 150 kg, and the elevator descends with an acceleration of 0.6 m / s ^ 2.
Initial data: m (mass of passengers in the elevator car) = 150 kg; a (the acceleration with which the lift descends) = 0.6 m / s2.
Reference data: according to the condition g (gravitational acceleration) ≈ 10 m / s2.
The force of pressure of passengers on the floor of the descending elevator car can be determined by the formula: F = P = m * (g – a).
Calculation: F = 150 * (10 – 0.6) = 150 * 9.4 = 1410 N.
Answer: Passengers press on the bottom of the descending elevator car with a force of 1410 N.
