Question

Грузовой лифт с находящимся в нем грузов движется равнозамедленно верх с ускорением 0.12 м/с^2. Если вес груза во время замедления равен 3458 Н,то его масса?

Answer 1

P=m(g-a);

m=P/(g-a);

m=357(кг).

Answer 2

Calculation of the Mass of the Load in a Freight Elevator

To calculate the mass of the load in the freight elevator, we can use Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration. In this case, the force acting on the load is equal to its weight.

Given: - Acceleration (a) = 0.12 m/s^2 - Weight (F) = 3458 N

We can use the formula:

F = m * a

where: - F is the force acting on the load (weight) - m is the mass of the load - a is the acceleration

Rearranging the formula to solve for mass (m), we have:

m = F / a

Substituting the given values, we get:

m = 3458 N / 0.12 m/s^2

Calculating this, we find that the mass of the load in the freight elevator is approximately:

m ≈ 28,816.67 kg

Therefore, the mass of the load in the freight elevator is approximately 28,816.67 kg.
