Which of the following statements can be explained byNewton's second law of motion ?

Answer»

to stop a heavy body (say truck), greater force is needed than to stop a light body (say motorcycle) in the same TIME if they are moving with same speed
for a body of given mass, the greater the speed, the greater the opposing force to stop the body in a particular time duration
to change the momentum of a body by given value, the force required is independent of time
the same force acting on TWO DIFFERENT bodies for same time causes the same change in momentum for the different bodies
