Question

Rank these automobiles based on the magnitude of their momentum before the brakes are applied, from largest to smallest.Rank from largest to smallest. To rank items as equivalent, overlap them. If the ranking cannot be determined, check the box below.

Answer 1

Step-by-step explanation

The magnitude of the momentum of an object is given by:

`p=mv`

where p is the momentum

m is the mass of the object

v is the mass of the object

so

Step 1

ind the momentum of aeach vehicle

a)

let

mass=1000 Kg

v=20 m/s

replace and calculate

`\begin{gathered} p=mv \\ P=1000\text{ Kg}\cdot20\text{ }(m)/(s) \\ P_1=20000Kg(m)/(s) \end{gathered}`

b

let

mass=2000 Kg

v=5 m/s

replace and calculate

`\begin{gathered} p=mv \\ P=2000\text{ Kg}\cdot5\text{ }(m)/(s) \\ P_2=10000Kg(m)/(s) \end{gathered}`

c

let

mass=1000 Kg

v=10 m/s

replace and calculate

`\begin{gathered} p=mv \\ P=1000\text{ Kg}\cdot10\text{ }(m)/(s) \\ P_3=10000Kg(m)/(s) \end{gathered}`

d)let

mass=500 Kg

v=20 m/s

replace and calculate

`\begin{gathered} p=mv \\ P=500\text{ Kg}\cdot20(m)/(s) \\ P_4=10000Kg(m)/(s) \end{gathered}`

e)xlet

mass=4000 Kg

v=5 m/s

replace and calculate

`\begin{gathered} p=mv \\ P=4000\text{ Kg}\cdot5(m)/(s) \\ P_5=20000Kg(m)/(s) \end{gathered}`

f)let

mass=500 Kg

v=10m/s

replace and calculate

`\begin{gathered} p=mv \\ P=500\text{Kg}\cdot10(m)/(s) \\ P_6=5000Kg(m)/(s) \end{gathered}`

Step 2

ow, raknk the automobiles based on the magnitude of the momentum( from the largest to smallest)

so

(automoblile 1 is the one on the left)

I hope this helps you
