Question

What is the mass of an object with a velocity of 24.1 m/s and a momentum of 28.3 kg m/s?​

Answer 1

1.17427...kg

Step-by-step explanation:

Assumptions: no friction, no air resistance, no internal resistance, and it is 1 dimensional travel for velocity.

p=mv, where p is momentum, m is mass, and v is velocity

28.3=24.1(m)

divide both sides by 24.1

you get 1.174273859

Answer 2

`\boxed {\tt 1.17427386 \ kilograms}`

Step-by-step explanation:

The formula for momentum is:

`p=mv`

From this formula, we know that mass can be found by dividing the momentum by the velocity.

`(p)/(v)=m`

The momentum is 28.3 kg m/s and the velocity is 24.1 m/s

`p=28.3 \ kg \ m/s \\v=24.1 \ m/s`

`(28.3 \ kg \ m/s )/(24.1 \ m/s) =m`

Divide. The meters per second or "m/s" will cancel each other out.

`(28.3 \ kg)/(24.1) =m`

`1.17427386 \ kg=m`

The mass of the object is 1.17427386 kilograms.
