What is the momentum of the cannon after firing a cannon ball?

The total momentum of the cannon and the cannon ball after being fired is also zero, with the cannon and cannon ball moving in opposite directions.

When a cannonball is fired from a cannon the force on the cannonball compared to the force on the cannon is?

Because Earth has a huge mass, we don’t sense its small acceleration. When a cannon is fired, there is an interaction between the cannon and the cannonball. The force the cannon exerts on the cannonball is exactly equal and opposite to the force the cannonball exerts on the cannon.

What is the velocity of the cannon?

Since the cannonball has a momentum of 300 kg m/s, the cannon will also have a momentum of 300 kg m/s in the opposite direction, aka it will recoil with a velocity of 3m/s.

Why does a cannon recoil after firing?

Newton’s third law of motion: Newton’s third law of motion states that every action has an equal and opposite reaction. So, from the above discussion we can conclude that a cannon after firing recoils due to Newton’s third law of motion.

What is recoil momentum?

In technical terms, the recoil is a result of conservation of momentum, as according to Newton’s third law the force required to accelerate something will evoke an equal but opposite reactional force, which means the forward momentum gained by the projectile and exhaust gases (ejectae) will be mathematically balanced …

When a cannonball is fired from a cannon the force the cannon exerts on the cannonball is exactly equal to the force the cannonball exerts on the cannon?

Newton’s third law states that for every action there must be an equal and opposite reaction, so the forces on the cannon and cannonball are equal in magnitude (but not direction). and the mass of the cannon is larger than the mass of the cannonball, so the acceleration is lesser for the cannon than for the cannonball.

When a cannon is fired are the forces on the cannonball and the cannon equal in magnitude are the accelerations of the two equal?

when a cannon is fired, are the forces on the cannonball and on the cannon equal in magnitude? are the accelerations of the two equal? the forces are equal. though the acceleration is not.

What is the total momentum of the cannon and shell before firing and after firing?

(i) The total momentum of both canon and shell before firing is zero, because both are at rest. (ii) According to the law of conservation of momentum, total momentum of the cannon and shell after firing is also zero.

How do you calculate the velocity of a cannon after firing?

Calculate the velocity of the cannon immediately after firing. total momentum of cannon and cannon ball after collision = 0 kg m/s – because momentum is conserved Momentum of cannon ball after firing = 4.0 × 120 = 480 kg m/s.

How do you find the momentum of a cannonball?

Find the momentum of the cannonball once it has been fired. The cannon must have equal momentum in the opposite direction for momentum to be conserved at zero kgm/s Taking the cannons velocity to be positive, and the motion of the cannonball in the other direction to be negative.

What is the conservation of momentum in physics?

Conservation of momentum explains why a gun or cannon recoils backwards when it is fired. When a cannon is fired, the cannon ball gains forward momentum and the cannon gains backward momentum. Before the cannon is fired (the ‘event’) the total momentum is zero. This is because neither object is moving.

What is the total momentum of the situation before the firing?

The total momentum of the situation before the firing is zero. This means that after the firing, the total must remain at zero. Find the momentum of the cannonball once it has been fired. The cannon must have equal momentum in the opposite direction for momentum to be conserved at zero kgm/s.
