Question

A car in moving with velocity 60 kmph along northward direction suddenly the driver of the car changes the direction of motion of the car along 30° north of East without changing its speed. Then find magnitude and direction of change in velocity​

Answer 1

Explanation:

V

b

= velocity of bus

V

c

= velocity of car

V

bc

=25

3

km/hr

now from relative velocity

∣

V

b

∣ =

(25)

2

+(25

3

)

2

= 50km/hr

for direction

tanθ=

25

25

3

=

3

so

′

θ

′

is from east direction

Therefore it will be at 30' east of north

Hence (A) is correct
