Question

*If a cannon has a mass of 500 kg and the cannonball is fired at a velocity of 0.25 m/s, what will be the momentum of the cannon?*

1️⃣ 20 kgm/s
2️⃣ 2550 kgm/s
3️⃣ 125 kgm/s
4️⃣ 0.125 kgm/s​

Answer 1

Explanation:

Velocity = 0.25m/s. So, we know that, p = mv. where p = momentum, m= mass and v = velocity. Therefore, momentum = 500*0.25 = 125.00 = 125 kg m/s.6 days ago

Answer 2

⇒ Given:

The mass of a cannon is 500 kg

The velocity at which it was fired was 0.25 m/s.

⇒ Given Options:

1️⃣ 20 kg m/s

2️⃣ 2550 kg m/s

3️⃣ 125 kg m/s

4️⃣ 0.125 kg m/s​

⇒ To Find:

The momentum of the cannon.

⇒ Solution:

It is given that the mass of the cannon is 500 kg and the velocity at which it is fired is 0.25 m/s.

As we are asked to find the momentum of the cannon, we first need to find the formula of momentum.

$\bf{\implies\:Momentum=mass\times\:velocity}$

That is:

$\bf{\implies\:Momentum=mv}$

So, applying the values we know into the equation:

$\sf{Momentum=500\times0.25}$

$\sf{Momentum=125\:kg\:m/s}$

The required correct option is:

3️⃣ 125 kg m/s ✔

Momentum:

The amount of motion a certain object has is termed as momentum. It is defined as the product of the mass of the object and its velocity. It is directly proportional to its quantities - the mass and velocity and an increases in momentum can be observed when either of these increases.
