A ball is dropped from a high rise platform at $\displaystyle \mathrm{t}=0$ starting from rest. After $\displaystyle 6$ seconds another ball is thrown downwards from the same platform with a speed $\displaystyle v$. The two balls meet at $\displaystyle \mathrm{t}=18 \mathrm{~s}$. What is the value of $\displaystyle v$ ?
(take $\displaystyle \mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2$)
Official answer
(2)
$\displaystyle 75$ m/s
