What is the momentum of a 0.1 kg hockey puck moving at 55 m/s?

Step-by-step Explanation:

Momentum is given by the product of mass and velocity of any object.

We have:

Then, Momentum:

= 0.1 kg × 55 m/s

= 5.5 kg m/s (Ans)

~

V₁ = initial volume of the gas = 2.0 L

P₁ = initial pressure on the container

T₁ = initial temperature = 400 K

V₂ = final volume of the gas = ?

P₂ = final pressure on the container = 2 P₁            (Since pressure is doubled)

T₂ = final temperature = 200 K

Using the equation

P₁ V₁/T₁ = P₂ V₂/T₂

inserting the values

P₁ (2)/(400) = (2P₁) V₂/(200)

(2)/(400) = (2) V₂/(200)

V₂ = 0.5 L

Hence the correct choice is

A. 0.5 L
