Which of the following situations involves the Newton's second law of motion?

(a) a force can stop a lighter vehicle as well as a heavier vehicle which are moving
(b) a force can accelerate a lighter vehicle more easily than a heavier vehicle which are moving
(c) a force exerted by a lighter vehicle on collision with a heavier vehicle results in both the vehicles coming to a standstill'
(d) a force exerted by a escaping air from a balloon in the downward direction makes the balloon to go upwards

Solution

(b) A force can accelerate a lighter vehicle more easily than a heavier vehicle which are moving.
Since, F = ma
⇒ a = F/m
Lesser the mass, higher the acceleration.
