Answer:
here is ur answer
given that
=speed v= 60 km/h
=time=
=t 1 =1h
=t2 = 30 min
= now ,distance travelled by a car in east direction
=D1=v X t1
=D1 =60 X 1
=D1 =60 km
now distance travelled by in south direction
=D2=v X t 2
=D2=60 X 1/2
=D2= 30 km
NOW, THE DISPLACEMENT FROM INITIAL POSITION
=D=root (D1)^2+(D2)^2
=D=root (60)^2+ ( 30) ^2
=D =root 3600 + 900
=D =root 4500
=D=30 root 5
hence, the displacement of car is from initial position is 30 root 5 m.
thank you mark me as brain list
