Question

Груз массой 60 кг опускают вертикально вниз с помощью троса с ускорением 1,2 м/с2. Определите силу упругости троса.

Answer 1

F=m*(g-a)=60*(9,8-1,2)=516 H

Answer 2

Calculation of the Spring Force

To determine the spring force in this scenario, we need to consider the mass of the object and the acceleration it experiences while being lowered vertically with the help of a rope.

Given: - Mass of the object (m) = 60 kg - Acceleration (a) = 1.2 m/s^2

The force acting on the object is the product of its mass and acceleration, according to Newton's second law of motion:

Force (F) = mass (m) × acceleration (a)

Substituting the given values:

Force (F) = 60 kg × 1.2 m/s^2

Calculating the force:

Force (F) = 72 N

Therefore, the spring force exerted by the rope is 72 N.
