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

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

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 =

And The momentum of Car B =

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   = 400 kg × 6 m/s

I.e   = 2400 kg m/s

Again ,

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

I.e   = 15 kg × 15 m/s

I.e   = 225 kg m/s

So, ∵  2400 kg m/s 225 kg m/s

∴      

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
