When a cannon is fired will the cannon and cannon ball will have the same amount of kinetic energy?

Yes, both have the same energy, but because cannon is heavier the cannon ball gets more momentum and thus greater velocity.


When a cannon is fired the cannon and cannon ball will have the same amount of kinetic energy?

No they won't. But they'll have the same momentum, in opposite directions.


A 60 gram bullet is fired from a gun with 3150 joule of kinetic energy what is its velocity?

A 60 gram bullet fired from a gun with 3150 joules of kinetic energy has a velocity of 324.04 meters per second or 1,063.12 feet per second. (This is about 725mph).


What are the energy transformations when a gun is fired?

There are a few energy transformations when a gun is fired. Some of these include potential to kinetic energy, chemical to mechanical energy, and chemical to electromagnetic energy.


When a bullet is fired upwards vertically it gains?

When a bullet is fired upwards vertically it gains kinetic energy.


Does a heavy arrow or a light arrow have more kinetic energy when shot from a compound bow?

A heavy arrow will have more kinetic energy when shot from a compound bow compared to a light arrow. Kinetic energy is determined by both the mass and velocity of an object. Although a heavy arrow may have a lower initial velocity, its greater mass compensates and results in higher kinetic energy than a lighter arrow.


How can energy be kinetic?

If you fired a bullet vertically upward, it would have kinetic energy at first, when it gets to the top of its travel this would all have been converted to potential energy.


How the energy is transferred as a catapult is fired?

The energy stored in the stretched rubber (or elastic) is converted into the kinetic energy of the missile.


When a buulet is fired upward verticallyit gains in?

It will gain potential energy, while losing kinetic energy.


What is the momentum of a 35 kg shell fired from a cannon with a velocity of 500 m per s?

Momentum=35*500=17500Ns


How do you convert potential energy into kinetic?

If you fired a bullet vertically upward, it would have kinetic energy at first, when it gets to the top of its travel this would all have been converted to potential energy.


A rocket that moves upward from earth's surface at escape velocity will?

Escape the earth's gravitational pull and continue out into space. However, a rocket does not need to be launched at the escape velocity as it can continue to accelerate as it climbs. A gun projectile would need to be fired with the escape velocity. In a perfect system with only the projectile and the Earth: If the projectile is fired with the exact escape velocity it will travel to infinity away from the Earth. Upon reaching infinitely far away from Earth the projectile would have zero velocity. All of its kinetic energy (movement) would be transferred to potential energy.
