A point moves with uniform acceleration and \( v_{1}, v_{2} \), and \( v_{3} \) denote the average velocities in the three successive
\( \mathrm{P} \) intervals of time \( t_{1}, t_{2} \), and \( t_{3} \). Which of the following relations is correct?
(1) \( \left(v_{1}-v_{2}\right):\left(v_{2}-v_{3}\right)=\left(t_{1}-t_{2}\right):\left(t_{2}+t_{3}\right) \)
(2) \( \left(v_{1}-v_{2}\right):\left(v_{2}-v_{3}\right)=\left(t_{1}+t_{2}\right):\left(t_{2}+t_{3}\right) \)
(3) \( \left(v_{1}-v_{2}\right):\left(v_{2}-v_{3}\right)=\left(t_{1}-t_{2}\right):\left(t_{1}-t_{3}\right) \)
(4) \( \left(v_{1}-v_{2}\right):\left(v_{2}-v_{3}\right)=\left(t_{1}-t_{2}\right):\left(t_{2}-t_{3}\right) \)
