Question

Рабочий, массой 40 кг, несёт мешок массой 10 кг. найдите с какой силой он действует на пол?​

Answer 1

F=mg
F=(40+10)*9,8=490 H

Answer 2

Calculation of the Force Exerted on the Floor

To find the force with which the worker is exerting on the floor, we can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration. In this case, the acceleration is the acceleration due to gravity, which is approximately 9.8 m/s^2.

The mass of the worker is given as 40 kg, and the mass of the bag is given as 10 kg. To find the total mass, we add the mass of the worker and the mass of the bag: 40 kg + 10 kg = 50 kg.

Using Newton's second law, we can calculate the force exerted on the floor:

Force = mass × acceleration Force = 50 kg × 9.8 m/s^2

Calculating this, we find that the force exerted on the floor is approximately 490 N.
