Question

Two bodies of masses 4kg and 5 kg are acted upon by the same force. If the acceleration of lighter body is 2m/s^2,then the acceleration of the heavier body is​

Answer 1

Given:-

Two bodies of masses 4kg and 5 kg are acted upon by the same force. If the acceleration of lighter body is 2m/s².

which means:

• Mass Of Lighter Body= 4kg
• Acceleration of Lighter Body= 2m/s²
• Mass Of Heavier Body= 5kg

To Find:-

• the acceleration of the heavier body.

Solution:-

Force On lighter Body= $mass \times acceleration$

$f = 4kg \times 2m {s}^{ - 2}$

$= > f = 8N$

We Know that the Same Force acting upon the Both body

$\therefore \: force \: on \: lighter \: body = force \: on \: heavier \: body$

$= > 8N = 5 \times \: acceleration$

$\therefore \: acceleration = \frac{8}{5} m {s}^{ - 2} = 1.6m {s}^{ - 2}$
