| **The body coordinate equation is x = 6 + 7t2. What is this movement? Write a formula for the dependence of body speed on time. What are the speed and coordinate of the body in 6 s?**

This equation is the equation of uniformly accelerated motion, the initial coordinate of the body is {6}. The body moves in the direction of the OX axis, because the projection is positive. S = a * t ^ 2/2. Consequently, a = 14m / c ^ 2.

v1 = a * t = 14 * 6 = 84m / s

s = 14 * 36/2 = 7 * 36 = 252m

Accordingly, the coordinate is x1 = 6 + 252 = 258

Answer: V = 84m / s ^ 2, x = 258
