A car moving with a speed of \( 40 \mathrm{~km} / \mathrm{h} \) can be stopped by applying brakes after at least \( 2 \mathrm{~m} \). If the same car is moving with a speed of \( 80 \mathrm{~km} / \mathrm{h} \)., what is the minimum stopping distance ?
- (1) \( 2 \mathrm{~m} \)
(2) \( 4 \mathrm{~m} \)
(3) \( 6 \mathrm{~m} \)
(4) \( 8 \mathrm{~m} \)
\( \mathrm{P} \)
