Question

Чему равна масса ящика, если я прикладываю силу 10 Н , расстояние от бревна до моих рук 1 м, а расстояние от бревна до середины ящика 20 см?

Answer 1

$M_1=M_2$
$F_1l_1=F_2l_2$
$m_1gl_1=F_2l_2 \Rightarrow m_1= \frac{F_2l_2}{gl_1}\\ m_1= \frac{10*1}{10*0,2} } =5$ кг

Answer 2

Calculating the Mass of the Box

To calculate the mass of the box, we can use the formula: force = mass × acceleration. In this case, the force applied is 10 N, and the distance from the log to the center of the box is 20 cm (or 0.2 m).

Applying the Formula

Using the formula force = mass × acceleration, we can rearrange it to solve for mass: mass = force / acceleration. In this case, the acceleration is due to gravity, which is approximately 9.81 m/s^2.

Calculation

So, the mass of the box can be calculated as follows: mass = force / acceleration = 10 N / 0.2 m = 50 kg.

Therefore, the mass of the box is 50 kg.
