+ 1. Equations of motion of particles.
+</p>
+<p style="text-align: center;">
+ $$
+{x_{1}(t) = v_{1}t, \quad x_{2}(t) = \frac{at^2}{2}}
+$$
+</p>
+<p>
+2. The velocity of the first particle and acceleration of the second particle are determined by the given dependence $v = f(t)$:
+</p>
+<p style="text-align: center;">
+$$
+{v_{1} = 2\; \frac{m}{s}}, \quad a \equiv 0.33\; \frac{m}{s^{2}}.
+$$
+</p>
+<p>
+3. Particle encounter condition:
+</p>
+<p style="text-align: center;">
+$$
+x_{1}(t_{z}) = x_{2}(t_{z}). \quad t_{z} = \frac{2v_{z}}{a} = 12\; c, \quad x_{z} = 24\; m.
+$$
