1.	The speedometer of a car moving eastward reads ` 50 km //h`. It passes another car which travels westward at `50 km//h`. (i) Do both the cars have same dpeed ? (ii) Do they have the same velocity ? (ii) What is the relative velocity of car ` Aw.r.t. car B`.
Answer» (i) Since, speed is a scalar quantity and speedometer reads instantaneous speed of the car, hence both the cars have same pseed. (ii) Since, velocity is a vector quantity, hence hothe the cars having opposite velocities as they are moving in opposite directions. (iii) Relativ e velocity of car `A w.r.t. car B` `=v_(A) + v_(B)` `= (50 km //h + 50 km //h)1 `= 100 km //h due east.
