Скорость 1.2 м в минуту

Ускорение 1.2 за минуту или же 2.4 за 2 минуты

Answer 2

Problem Analysis

We are given that a body has completed a circular path with a radius of 2.4 meters in 2 minutes. We need to find the speed and acceleration of the body.

Speed Calculation

To find the speed of the body, we can use the formula:

Speed = Distance / Time

In this case, the distance traveled by the body is equal to the circumference of the circle, which can be calculated using the formula:

Circumference = 2 * π * Radius

Let's calculate the speed using the given information.

Speed Calculation:

The radius of the circle is given as 2.4 meters. Using this information, we can calculate the circumference of the circle using the formula mentioned above:

Circumference = 2 * π * 2.4

Now, we can calculate the speed using the formula:

Speed = Circumference / Time

Substituting the values, we get:

Speed = (2 * π * 2.4) / 2

Let's calculate the speed.

Speed Calculation:

The radius of the circle is given as 2.4 meters. Using this information, we can calculate the circumference of the circle using the formula mentioned above:

Circumference = 2 * π * 2.4

Now, we can calculate the speed using the formula:

Speed = Circumference / Time

Substituting the values, we get:

Speed = (2 * π * 2.4) / 2

Using a calculator, we find that the speed is approximately 7.54 meters per minute.

Acceleration Calculation

To find the acceleration of the body, we need to know the change in speed and the time taken. However, the problem does not provide any information about the change in speed or the time taken. Therefore, we cannot calculate the acceleration with the given information.

Summary

- The speed of the body is approximately 7.54 meters per minute. - The acceleration of the body cannot be calculated with the given information.
