Two cars of unequal masses use similar tyres. If they are moving at the same initial speed, the minimum stopping distance

Question

is same for both cars Given: both the cars have same initial speed. Let the masses of the two cars be m1 and m2. Frictional force on car with mass m1 = μm1 g So, the deceleration due to frictional force =(mum_1g)/m_1=mug Frictional force on car with mass m2 = μm2 g So, the deceleration due to frictional force =(mum_2g)/m_2=mug As both the acceleration are same, from the second equation of motion s =ut+$\frac{1}{2}$at^2 Thus, we can say that both the cars have same minimum stopping distance.
