Question

Which object has more momentum a 400 kg car traveling at 6 m/s or a 15 kg Cannonball traveling at 15 m/s?​

Answer 1

The car having 400 kg and speed 6 m/s have more momentum than The car having 15 kg and speed 15 m/s .

Step-by-step explanation:

Given as :

The mass of Car A = 400 kg

The velocity of Car A = 6 m/s

The mass of Car B = 15 kg

The velocity of Car B = 15 m/s

Let The momentum of Car A =
`M_1`

And The momentum of Car B =
`M_2`

Now ,

Since momentum is the property of moving body , and it is defined as the products of mass velocity of body .

I.e, M = mass × velocity

So, The momentum of Car A = mass of Car A × velocity of Car A

I.e
`M_1` = 400 kg × 6 m/s

I.e
`M_1` = 2400 kg m/s

Again ,

So, The momentum of Car B = mass of Car B × velocity of Car B

I.e
`M_2` = 15 kg × 15 m/s

I.e
`M_2` = 225 kg m/s

So, ∵ 2400 kg m/s
`>` 225 kg m/s

∴
`M_1`
`>`
`M_1`

so, Momentum of car A more than momentum of car B

Hence The car having 400 kg and speed 6 m/s have more momentum than The car having 15 kg and speed 15 m/s . Answer
