Tell us about the system of actions (algorithm) when solving problems in dynamics.

1 Select an inertial reference system.
2 Draw the vectors of forces and accelerations of the body in the figure.
3 Write the equation of Newton’s second law in vector form and in projection onto the coordinate axes.
4 Express the modules of forces in terms of the corresponding physical quantities and write down the formulas for determining the displacement, speed and acceleration of a body, necessary for solving.
5 Solve the system of equations for the desired physical quantity.
6 Substitute numerical data and record the answer.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
