Question

The velocity of a aeroplane is made twice. What happen to it's momentum? What will happen to it's Kinetic Energy? Is the energy conserved?

Answer 1

Answer:

Conserving Momentum If the net force acting on an object is zero, then the linear momentum is constant. In an elastic collision (such as a superball hitting and rebounding from the ground), no kinetic energy is lost.

All of that energy is still in the object, so we say that energy was conserved.

Answer 2

Hiiii dude....

When velocity of aeroplane is made twice, its momentum will becom twice. The momentum of plane and that of air will remain conserved. This is because when momentum of plane becomes twice, the momentum of air in the opposite direction will also become twice.Total energy shall remain conserved.
