Question

A bullet has a mass of 8 grams and a muzzle velocity of 340m/sec. A baseball has a mass of 0.2kg and is thrown by the pitcher at 40m/sec. What is the momentum of the baseball? What is the momentum of the bullet?

Answer 1

Momentum of bullet

`P = 2.72 kg m/s`

momentum of baseball

`P = 8 kg m/s`

Step-by-step explanation:

As we know that momentum is defined as the product of mass and velocity

here we know that

mass of the bullet = 8 gram

velocity of bullet = 340 m/s

momentum of the bullet is given as

`P = mv`

`P = ((8)/(1000))(340)`

`P = 2.72 kg m/s`

Now we have

mass of baseball = 0.2 kg

velocity of baseball = 40 m/s[/tex]

momentum of baseball is given as

`P = (0.2)(40)`

`P = 8 kg m/s`
