Answer 1

С
Основная задача механики, как неоднократно указывается в учебнике «Физика 8», — определять положение (координаты) движущегося тела в любой момент времени.

Answer 2

Main Task of Mechanics

The main task of mechanics involves:

A) Finding the functions x=f(t), y=g(t), z+h(t) - This involves finding the functions that describe the position of an object in three-dimensional space as a function of time. It is a fundamental aspect of mechanics to understand the motion of objects in space and time.

B) Finding the function x(t) - This task involves finding the function that describes the position of an object in one-dimensional space as a function of time. This is essential for understanding the motion of objects along a straight line.

C) Finding the coordinates of a body - Mechanics also involves determining the coordinates of a body in space, which is crucial for analyzing its motion and behavior.

D) Finding the velocity of a body - Another important task of mechanics is to determine the velocity of a body, which is the rate of change of its position with respect to time. This is essential for understanding how fast an object is moving and in what direction.

E) Finding the acceleration of a body - Mechanics also involves determining the acceleration of a body, which is the rate of change of its velocity with respect to time. Understanding acceleration is crucial for analyzing how the speed of an object is changing over time.

These tasks are fundamental to the study of mechanics and are essential for understanding the behavior of objects in motion.
