| The dependence of the path on time for a rectilinear moving body has the form: S (t) = 2t + t ^ 2. What is the acceleration of the body?
In general, the equation of the path for uniformly accelerated rectilinear motion is written as follows:
S (t) = v0 * t + a * t ^ 2/2;
Thus, the coefficient before t ^ 2 is 0.5a. Using this ratio, we find the acceleration:
0.5a = 1;
a = 2.
Units of measurement are not specified in the conditions of the problem, therefore, they are also absent in the answer.
Answer: a = 2.
