Question

A force of 12N produces an acceleration of 3 m/s2

on a body and an acceleration of 4 m/s2

on another body of different mass. What will be the acceleration if the same force is applied

on the combined mass?​

Answer 1

Answer:

On first body,

force applied on the body=12N

acceleration produce =3m/s^2

mass of a body =force applied/acceleration due to gravity

mass of the body =12/3

=4kg

On second body,

force applied on the body=12N

acceleration produce=4m/s^2

mass of the body=force applied/acceleration due to gravity

mass of the body=12/4

=3kg

now,

on adding the two body mass =(3+4)kg

=7kg

mass of the body=7kg

force applied=12N

acceleration =force applied/mass of the body

=12/7

=1.71m/s^2
