Question

The diagram below shows the velocity vectors for two cars that are moving relative to each other.

From the frame of reference of car 1, what is the velocity of car 2?

Answer 1

70 m/s east

Step-by-step explanation:

Answer 2

The answer is "
`5 \ (m)/(s) \ west`"

Step-by-step explanation:

`\to \vec{V_1} = (25 (m)/(s)) (\hat{-i})\\\\\to \vec{V_2} = (20 (m)/(s)) (\hat{-i})\\\\`

velocity of car | respect to car :

`\to \vec{V_(12)} = \vec{V_1} - \vec{V_2}\\\\`

`=\vec{-25} \hat{i}+ \vec{20} \hat{i}\\\\= 5 \ (m)/(s) \ west`
