Question

The mass of the cannon is 500kg and it recoils with a speed of 0.25 m/s.What is the momentum of the cannon?

Answer 1

Hello friend

___________________________

Let's write the given::

mass of the cannon = 500 kg

recoil speed = 0.25 m/s

And we have to find:

Momentum= ??

So, we know that

Momentum = m x v

Momentum = 500 x 0.25

Momentum = 125 kg m/s.


Therefore,the momentum of the cannon is 125 kg m/s.


I hope this will helps you...

Thanks ....... :)

Answer 2

Answer:

The momentum of the cannon is 125 kg m/s.

Explanation:

Let's write the given::

mass of the cannon = 500 kg

recoil speed = 0.25 m/s

And we have to find:

Momentum = m x v

Momentum = 500 x 0.25

Momentum = 125 kg m/s.

In Newtonian mechanics, linear momentum, translational momentum, or truely momentum is the manufactured from the mass and speed of an item. it's far a vector quantity, possessing a importance and a direction. If m is an item's mass and v is its velocity (also a vector quantity), then the item's momentum p is : {displaystyle mathbf {p} =mmathbf {v} .}mathbf{p} = m mathbf{v}.

In the global device of devices (SI), the unit of measurement of momentum is the kilogram metre in line with second (kg⋅m/s), which is equivalent to the newton-second.

Newton's second regulation of motion states that the fee of alternate of a body's momentum is equal to the net force acting on it. Momentum depends on the frame of reference, but in any inertial body it's miles a conserved amount, meaning that if a closed system is not tormented by outside forces, its overall linear momentum does no longer change. Momentum is also conserved in special relativity (with a changed system) and, in a changed shape, in electrodynamics, quantum mechanics, quantum subject concept, and popular relativity. it's miles an expression of one of the essential symmetries of space and time: translational symmetry.

Advanced formulations of classical mechanics, Lagrangian and Hamiltonian mechanics, permit one to choose coordinate structures that incorporate symmetries and constraints. In those structures the conserved quantity is generalized momentum, and in standard that is one of a kind from the kinetic momentum defined above. The concept of generalized momentum is carried over into quantum mechanics, wherein it turns into an operator on a wave function. The momentum and role operators are associated by way of the Heisenberg uncertainty precept.
