A man throws a ball vertically upward and it rises through \( 20 \mathrm{~m} \) and returns to his hands. What was the
P initial velocity \( (u) \) of the ball and for how much time

W (T) it remained in the air \( \left[g=10 \mathrm{~m} / \mathrm{s}^{2}\right] \)
(1) \( u=10 \mathrm{~m} / \mathrm{s}, \mathrm{T}=2 \mathrm{~s} \)
(2) \( u=10 \mathrm{~m} / \mathrm{s}, \mathrm{T}=4 \mathrm{~s} \)
(3) \( u=20 \mathrm{~m} / \mathrm{s}, \mathrm{T}=2 \mathrm{~s} \)
(4) \( u=20 \mathrm{~m} / \mathrm{s}, \mathrm{T}=4 \mathrm{~s} \)
