Question

the mass of two bodies are in the ratio of 3 : 4 .on applying a certain force on the first body, an acceleration of 6 m/s² is produced .what will be the acceleration in the second body when the same is applied in it

Answer 1

Let the masses be 3k and 4k.
Acceleration produced in body 1 = 6m/s^2.
Thus F1 =ma = 18k.
Then acceleration produced by the same force in second body is 18k÷4k
=4.5m/s^2.
Hope this answers it.
