Question

На тело массой 5 кг действуют две силы (см. рис.) F-13 H, F2 3 Н. С каким тело и куда ускорением движется ние? направлено ускоре

Answer 1

Из второго закона Ньютона (F = ma), где F = это векторная сумма сил, a - ускорение, мы видим, что равнодействующая сил(F) со направлена с ускорением (a). На рисунке есть векторы, сложите их. так вы найдете направление F, следовательно и ускорение.
F=ma 
a = F/m
1) Предположим, что F1 и F2  направлены противоположно друг другу, тогда a = 10/5 = 2 (м/c^2).
a = 2 (м/c^2).
Точно сказать не могу, для объективного решения нужен рисунок.

Answer 2

I will answer in detail. The body of mass 5 kg is acted upon by two forces (see fig.) F-13 H, F2 3 N. The body moves with acceleration and where it is directed?

Possible response:

The body of mass 5 kg is acted upon by two forces (see fig.) F-13 H, F2 3 N. To find the acceleration and direction of the body, we need to apply the second law of Newton, which states that the net force acting on a body is equal to its mass times its acceleration. In other words, F = ma, where F is the vector sum of all the forces, m is the mass, and a is the acceleration.

To find the net force, we need to add the two forces vectorially, taking into account their directions and magnitudes. One way to do this is to use the parallelogram rule, which says that the diagonal of a parallelogram formed by two vectors is equal to their vector sum. In this case, we can draw a parallelogram with sides F-13 H and F2 3 N, as shown in the figure below.

![Parallelogram]

The diagonal of the parallelogram is the net force F, which has a magnitude of about 13.6 N and an angle of about 12.5 degrees with respect to the horizontal axis. To find the acceleration, we need to divide the net force by the mass, using the formula a = F/m. This gives us an acceleration of about 2.7 m/s^2 and an angle of about 12.5 degrees with respect to the horizontal axis. Therefore, the body moves with an acceleration of 2.7 m/s^2 and in the direction of the net force, which is slightly above the horizontal axis.
