Question

Двое мальчиков везут третьего на санках, прилагая в направлении движения силы 300 Н и 100 Н. Чему равна равнодействующая сила?

Answer 1

Так как мальчики тянут в одну сторону их силы складываются
300Н + 100Н = 400Н
Вот и все

Answer 2

Calculating the Resultant Force

To calculate the resultant force, we can use the formula for finding the resultant of two forces:

Resultant Force (R) = √(F1^2 + F2^2 + 2F1F2cosθ)

Where: - F1 = 300 N (force applied by the first boy) - F2 = 100 N (force applied by the second boy) - θ = the angle between the forces (not provided)

Since the angle between the forces is not provided, we'll assume that the forces are acting in the same direction, making the angle between them 0 degrees. In this case, the formula simplifies to:

Resultant Force (R) = √(300^2 + 100^2 + 2*300*100*cos(0°))

Calculating the Resultant Force (Continued)

Now, let's calculate the resultant force using the given forces and the simplified formula:

Resultant Force (R) = √(300^2 + 100^2 + 2*300*100*cos(0°))

Resultant Force (R) = √(90000 + 10000 + 60000)

Resultant Force (R) = √160000

Resultant Force (R) = 400 N

So, the resultant force when two boys apply forces of 300 N and 100 N in the same direction is 400 N.
