Question

С земли запущен метеорологический зонд массой 2,7 кг, которому необходимо подняться на высоту 30–40 км. 800px-Wetterballon_Nutzlast_Start_2004-09-10.jpg Во время взлёта на зонд действует Архимедова сила, равная 33,1 Н. Ускорение свободного падения — 9,8 мс2. Чему равна сила тяжести, действующая на зонд? Fтяж = Н (округли до десятых). Чему равно ускорение движения зонда в момент взлёта? a = мс2 (округли до сотых).

Answer 2

Calculation of Weight Force on the Balloon

To calculate the weight force acting on the balloon, we can use the formula:

Weight Force (Fтяж) = mass (m) x acceleration due to gravity (g)

Given that the mass of the balloon is 2.7 kg and the acceleration due to gravity is 9.8 m/s^2, we can substitute these values into the formula:

Fтяж = 2.7 kg x 9.8 m/s^2

Calculating this, we find:

Fтяж = 26.46 N

Therefore, the weight force acting on the balloon is approximately 26.46 N.

Calculation of Acceleration of the Balloon during Ascent

To calculate the acceleration of the balloon during ascent, we can use Newton's second law of motion:

Force (F) = mass (m) x acceleration (a)

In this case, the force acting on the balloon during ascent is the sum of the weight force (Fтяж) and the buoyant force (FАрх):

F = Fтяж + FАрх

Given that the buoyant force (FАрх) is equal to 33.1 N and the weight force (Fтяж) is 26.46 N, we can substitute these values into the equation:

33.1 N = 26.46 N + m x a

Simplifying the equation, we have:

a = (33.1 N - 26.46 N) / m

Substituting the mass of the balloon (m = 2.7 kg) into the equation, we can calculate the acceleration:

a = (33.1 N - 26.46 N) / 2.7 kg

Calculating this, we find:

a ≈ 2.46 m/s^2

Therefore, the acceleration of the balloon during ascent is approximately 2.46 m/s^2.
