| Hints |
Capture when v(t) = 0.79 x v_term. Compute v_term from physics, find t where v(t)=f*v_term, then y(t)=capture_row. capture_row is NOT given. Derive it from the velocity condition. Physics: g=9.80, m=0.89, drag=linear, Cd=0.862173. Each column scrolls independently. Compute capture_time, then scroll offset per column. Find the character at capture_y at capture_time in each column. Submit the 6-character word.
