Question

На тело массой 20 кг действует три силы.Сила 23 H направлена вниз,сила 17H-вверх,а третья сила-горизонтально.Найдите модуль третьей силы,если тело движеться с ускорением 0,5 м/с2.

Answer 1

Ma=F1+F2+F3
F3=ma-(F1+F2)
F3=0,5*20-(17+(-23))=16
(F2 отрицательна, т.к направлена вниз)

Answer 2

Calculating the Module of the Third Force Acting on a Body

To calculate the module of the third force acting on a body with a mass of 20 kg and moving with an acceleration of 0.5 m/s^2, we can use the following formula:

F = ma

Where: - F is the force - m is the mass of the body - a is the acceleration

Applying the Formula

Using the given information: - Mass (m) = 20 kg - Acceleration (a) = 0.5 m/s^2

We can calculate the force (F) acting on the body.

Calculation

F = ma F = 20 kg * 0.5 m/s^2 F = 10 N

Therefore, the module of the third force acting on the body is 10 N.
