Решение задачи по физике раздел 53 пункт 9 механика

9. From the helicopter, hanging motionless at a certain height above the ground, dropped load mass m = 100 kg. Assuming that the force of air resistance is proportional to the speed, to determine how much longer Δt acceleration a cost will be equal to half the acceleration of gravity. The drag coefficient k = 10 kg / s.
