Question

Тело массой 2 кг движется со скоростью 2 м/с и ускорением 3м/с.Каков модуль равнодействующей сил,действующих на тело?

Answer 1

Равнодействующая всех сил по 2 закону ньютона равна F=ma=2*3=6 Н

Answer 2

Calculation of the Resultant Force

To calculate the magnitude of the resultant force acting on an object, 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. Mathematically, this can be expressed as:

F = m * a

where: - F is the resultant force - m is the mass of the object - a is the acceleration of the object

In this case, the mass of the object is given as 2 kg and the acceleration is given as 3 m/s². Plugging these values into the equation, we can calculate the magnitude of the resultant force:

F = 2 kg * 3 m/s²

Calculating the product, we find:

F = 6 kg·m/s²

Therefore, the magnitude of the resultant force acting on the object is 6 N.

Conclusion

The magnitude of the resultant force acting on the object is 6 N.
