Question

a car is moving to east with velocity 3m/s the bus appearing to car to move along the north. Now the car moves along east with velocity 4m/s ,the bus appearing to car to move along 30° West to North . then find the actual velocity of bus?​

Answer 1

Answer:

50km/h,30 o east of northV b

= velocity of bus V c

= velocity of carV bc

=25 3km/hr

now from relative velocity∣ V b l

= (25) 2+(25 3 ) 2

= 50km/hrfor direction tanθ= 2525 3

= 3

so ′ θ , is from east direction

Therefore it will be at 30' east of north

Hence (A) is correct
