Q. A motor cycle and a car are moving on a horizontal road with the same velocity. If they are brought to rest by the application of brakes, which provided equal retardation, then
A) Motor cycle will stop at shorter distance
B) Car will stop at a shorter distance
C) Both will stop at the same distance
D) Nothing can be predicted
Explanation
(c) $s = (v^{2} - u^{2})/2a$ is independent of mass
Hence both will stop at the same distance
