Question

Instructions: 1) write out the question 2) work out the solution 3) Explain in words how you would know to do that1. What is the momentum of a 5.0 g bullet with a velocity of 500 m/s?

Answer 1

Given data:

The mass of bullet is m=5.0 g.

The velocity fo bullet is v=500 m/s.

The formula for the momentum is given by,

`p=mv`

Substitute the given values in above equation,

`\begin{gathered} p=(5g*\frac{1kg}{1000\text{ g}})((500m)/(s)) \\ p=(2.5kgm)/(s) \end{gathered}`

Thus, the momentum of the bullet is 2.5 kgm/s.

According to the definition of momentum, "It is the product of mass and velocity". Therefore, the momentum of moving body can be calculated by multiplying the mass of the body and velocity at which the body is moving.

So, that is how we know how to calculate the momentum of the body.
