Question

8) A spy report about a suspected car reads as
follows. "The car moved 2.00 km towards
east, made a perpendicular left turn, ran for
500m, made a perpendicular right turn, ran
for 4.00 km and stopped". Find the
displacement of the car.

​

Answer 1

Answer:

"ANSWER

Mention East by i

west by −i

North by j

and South by −j

Now coming to motion initially 2km towards east so 2i

Then left turn means north and 0.5km so 0.5j

Then a right turn means again east and 4.0km so 4i

net displacement will be 2i+0.5j+4i=6i+0.5j

magnitude will be

6

2

+0.5

2

=6.02km
