A blue ball is thrown upward with an initial speed of \( 21.4 \mathrm{~m} / \mathrm{s} \), from a height of \( 0.7 \) meters above the ground. \( 2.6 \) seconds after the blue ball is thrown, a red ball is thrown down with an initial speed of \( 7.4 \mathrm{~m} / \mathrm{s} \) from a height of \( 25.7 \) meters above the ground. The force of gravity due to the earth results in the balls each having a constant downward acceleration of \( 9.81 \mathrm{~m} / \mathrm{s}^{2} \). 1) What is the speed of the blue ball when it reaches its maximum height? \( \mathrm{n} / \mathrm{s} \) rou currently have 1 submissions for this question.

(Hint: Find the position and velocity of the blue ball at the time the red ball was thrown, and use them as the blue ball's initial positon and velocity.)
