32.5 kg of air

Explanation:

To calculate the mass of the air, we use the density formula:

density = mass / volume

mass = density × volume

density of air = 1.3 kg/m³

volume = 5 × 3 × 2 = 25 m³

mass of the air = 1.3 kg/m³ × 25 m³

mass of the air = 32.5 kg

How does the momentum of a 75 kilogram stationary football player compare with that of a 70 kilogram player moving at a velocity
pashok25 [27]
Momentum of an object = (its mass) x (its speed) .

Since speed is a factor of momentum, an object that
isn't moving doesn't have any.

-- The moving player has momentum. 

-- The stationary one doesn't.

A cat is chasing a bird across your yard. It covers 14.6 m in 2.8 s. What is its average velocity?
ololo11 [35]

Answer:

<h2>5.21 m/s</h2>

Explanation:

The average velocity of the cat can be found by using the formula

v =  \frac{d}{t}  \\

d is the distance

t is the time taken

From the question we have

v =  \frac{14.6}{2.8}  \\  = 5.2142857..

We have the final answer as

<h3>5.21 m/s</h3>

Hope this helps you
