A car moving with a speed of \( 40 \mathrm{~km} / \mathrm{h} \) can be stopped by applying brakes after atleast \( 2 \mathrm{~m} \). If the
P same car is moving with a speed of \( 80 \mathrm{~km} / \mathrm{h} \), what is

W the minimum stopping distance?
(a) \( 4 \mathrm{~m} \)
(b) \( 6 \mathrm{~m} \)
(c) \( 8 \mathrm{~m} \)
(d) \( 2 \mathrm{~m} \)
