Calculate the average velocity of the particle whose position vector c

1.	Calculate the average velocity of the particle whose position vector changes from vec(r_(1))=5hati+6hatj" to "vec(r_(2))=2hati+3hatj in a tine 5 second.
Answer» Solution :Average velocity: `vecV_(avg)=(Deltar)/(DELTAT)=(vecr_(2)-vecr_(1))/(dt)=((2-5)HATI+(3-6)HATJ)/(5)` `vecV_(avg)=(-3hati-3hatj)/(5)=(-3)/(5)(hati+hatj)`
