**This is a Question with 3 parts.Any help will be appreciated.Also can you explain what is magnitude of velocity?**

**1. Two cars approach each other; both cars are**

moving westward, one at 76 km/h, the other

at 66 km/h.

What is the magnitude of the velocity of the

first car relative to (in the frame of reference

of) the second car? Answer in units of km/h.
