Question

Solve this:
3 A car moves 2 00 km towards east, makes a perpendicular left turn
and travels 500 m, makes a perpendicular right turn and travels 4
00 km and finally stops Find the displacement of the car
4 A body covers an arc of a circle of radius 'r', subtending an
angle of 120° at the centre of the circle What is the magnitude
of the displacement of the body?

Dear Student ,

The displacement of the car is represented by
AD→
AD→=2i^+0 5j^+4i^      =6i^+0
5j^

Magnitude of AD→ 
is given by

AD=AE2+DE2      =62+0
52      =36+0 25=6
02 km

Now, tan θ=DEAE=112
⇒θ=tan-1 112

Hence, the displacement of the car is 6 02 km along the
direction tan-1 112 
with positive the 
x-axis
