Solution to problem 7.8.2 from the collection of Kepe O.?. consists in determining the acceleration modulus of a point along a given vector.

The acceleration vector of a point is given as a = 2.5n + 3.5?, where n and ? - unit vectors of a natural trihedron.

To determine the acceleration modulus of a point, it is necessary to calculate the length of the vector a, that is, its Euclidean norm.

The length of the vector a is calculated by the formula: |a| = sqrt(a1^2 + a2^2 + a3^2), where a1, a2, a3 are the coordinates of vector a.

Replacing the coordinates with the values ​​from the problem, we get:

|a| = sqrt((2.5)^2 + (3.5)^2) = sqrt(6.25 + 12.25) = sqrt(18.5) ≈ 4.30

Thus, the answer to problem 7.8.2 from the collection of Kepe O.?. equals 4.30.
