Question

if an object if mass m is moving space with constant velocity abd suddenly if an object come in its path, the object moving pushes another object with some force. but according to F=MA. force is 0.then why does the object move?? ​

Answer 1

Answer:

As the body is moving with constant velocity suppose 'V' then it has no acceleration so force will be 0 for first body.

But for the second body as it has initial velocity 0 but it will attain a velocity V after colliding with body A ,

so there will be a change in velocity which will be equal to acceleration in time t.

So they will be force is equal to mass into acceleration

which can be written as f = mA
