Question

A shot fired from cannon explodes in air. What will be the change in the momentum and energy ?​

Answer 1

Answer:

Change in the momentum and energy a shot fired from cannon explodes in air what will be the change in the momentum ......

Answer 2

The change in momentum is zero and energy increases.

Explanation:

Momentum :

Momentum is equal to the multiplication of mass and velocity.

In mathematically.

$P=mv$

Where, m = mass

v = velocity

We need to calculate a momentum when a shot fired from cannon explodes in air

Then the change in momentum is zero of the cannon because the momentum of remains conserved of the sysetem.

But the kinetic energy of the cannon increases due to the conversion  of chemical potential energy of explosion in the shot into kinetic energy.

Hence, The change in momentum is zero and energy increases.
