Question

The linear momentum is a constant when the mass varies inversely of the velocity. If the velocity is 16 meters per second

and the object weighs 450 kilograms, what is the weight for an object with a velocity of 12 meters per second?
400 kilograms
600 kilograms
6,400 kilograms
7,200 kilograms

Answer 1

The weight for an object with a velocity of 12 meters per second is 600 kilograms

Explanation:

Formula of linear momentum : p = mv

where p is the momentum

m = mass

v = velocity

If the velocity is 16 meters per second and the object weighs 450 kilograms

Substitute the values

`p = 16 * 450`

We are supposed to find the weight for an object with a velocity of 12 meters per second

So, p = 12m

We are given that The linear momentum is a constant when the mass varies inversely of the velocity.

So,
`16 * 450 = 12 m`

`(16 * 450)/(12)=m`

600 = m

So,the weight for an object with a velocity of 12 meters per second is 600 kilograms
