A balloonist happens to drop his metal ballpoint pen from his balloon as he is taking notes on his flight. Because his pen has a streamlined shape, air resistance has little effect on its fall. The pen strikes the ground at 22 m/s. How high was the balloon?
(Points : 6)
25 m
49 m
850 m
9,500 m

Best ResponseYou've already chosen the best response.0\(\vec v_f^2=\vec v_i^2+2\vec a \cdot \vec S\) since \(\vec v_i=0\hat j\),\(\vec v_f=22\hat j\),\(\vec a=10\hat j \), plug it in to get, \((22\hat j)^2=2(10\hat j) \cdot \vec S\) \(\vec S=24.2\hat j\) do you need further help?
