Answer :
the angle covered by man is 10/15 rad
1 rad=180/pi degrees
10/15 rad=(180/pi)*(10/15) degrees=38.197 degrees
Now displacement is given by cosine law
let l be displacement
[tex]l^2=2r^2-2r^2cos(38.197)=2(100)(1-cos(38.197))=42.823[/tex]
[tex]l=6.5434 cm[/tex]
is the displacement
1 rad=180/pi degrees
10/15 rad=(180/pi)*(10/15) degrees=38.197 degrees
Now displacement is given by cosine law
let l be displacement
[tex]l^2=2r^2-2r^2cos(38.197)=2(100)(1-cos(38.197))=42.823[/tex]
[tex]l=6.5434 cm[/tex]
is the displacement
Angle Covered man = 10/15
rad 1 rad = 180/pi degrees
10/15 rad =(180/pi)*(10/15) degrees=38.197 degrees
Now displacement is given by cosine law
let l be displacement l^2=2r^2-2r^2cos
(38.197)=2(100)(1-cos(38.197))=42.823
displacement = l=6.5434 cm
rad 1 rad = 180/pi degrees
10/15 rad =(180/pi)*(10/15) degrees=38.197 degrees
Now displacement is given by cosine law
let l be displacement l^2=2r^2-2r^2cos
(38.197)=2(100)(1-cos(38.197))=42.823
displacement = l=6.5434 cm
