Question

Bodies A and B having masses m1

and m2

(m1

> m2

) respectively have same linear

momentum. Which of the two is moving faster ? Explain your answer with relevant

mathematical relations.

Answer 1

if both the bodies are provided with the same force then m2 will move faster cause it's mass is less
According to Newton's second law of motion
F=ma ,we can drive ...a=F/m
when force will be equal in both cases then the body with less mass will move faster
For eg let the force be 12N and the mass of body m1 be 4 and mass of body m2 be 3
so acceleration in body m1 will be...
a=F/m=12/4=3
acceleration in body m2 will be...
a=F/m=12/3=4
So from the above example we get that lesser the mass of a body more will be the acceleration
