The unit vector r hat that points in the direction of r is g

The unit vector r hat that points in the direction of r is given by r hat=r/ |r|. If r = (-8.60)î + (9.70), find r hat. Enter the x component, then the y component of r hat.

Solution

Here ,

r = - 8.6 i + 9.70 j

|r| = sqrt(8.6^2 + 9.7^2)

|r| = 12.96

r hat = r/|r|

r hat = (-8.6 i + 9.70 j)/12.96

r hat = - 0.663 i + 0.748 j

for the r hat , x - component = - 0.663

y component = 0.748
