Question

Show that the velocity of the centre of mass of a moving isolated systems remains

Answer 1

M for mass

And V for velocity.

When there is not external force the acceleration of body is zero.

The velocity of the body will be ′v′

Force= rate of change of momentum

⇒F=d(mv)/dt

⇒m(dv/dt)=F

The external force F=0

M(dv/dt)=0

dv/dt=0

M is not zero

So this proves that velocity will always be constant in such scenario.

Hope this helps plz mark as brainliest.

Answer 2

Explanation:

velocity will be remain zero when the total force of the system will be zero
