Question

Шарик падает в воздухе. Найти массу шарика, если сила сопротивления воздуха 0,8 Н, а равнодействующая сила 6 Н.

Answer 1

R=mg-Fсопр

mg=R+Fсопр=6+0,8=6,8 Н.  m=6,8/g=6,8/9,8=0,69 кг

Answer 2

Finding the Mass of the Falling Ball

To find the mass of the falling ball, we need to consider the forces acting on it. In this case, we know the force of air resistance is 0.8 N and the resultant force is 6 N.

The resultant force is the vector sum of all the forces acting on an object. In this case, it is the sum of the force of gravity and the force of air resistance. Since the ball is falling, we can assume the force of gravity is acting downwards.

Using Newton's second law of motion, we can express the resultant force as the product of mass and acceleration:

Resultant force = mass × acceleration

In this case, the acceleration is due to gravity and is approximately 9.8 m/s^2. Therefore, we can rewrite the equation as:

6 N = mass × 9.8 m/s^2

To find the mass, we can rearrange the equation:

mass = 6 N / 9.8 m/s^2

Calculating this, we find that the mass of the falling ball is approximately 0.61 kg.
