A man moves in the following manner in X-Y plane. Find the magnitude of displacement of man from origin as shown in figure.

Text Solution

Verified by Experts

`vec(r)_(1)=4hat(i)`
`vec(r)_(2)=5 cos37^(@)hat(i)+5sin 37^(@)hat(j)`
`vec(r)_(2) =4hat(i)+3hat(j)`
Resultant vector
`vec(r)=vec(r)_(1)+hat(r)_(2)`
`=8hat(i)+3hat(j)`
