Plz do it plzzzzzzz​

Answer 1

Step-by-step explanation:

Let velocity of car = a

Let velocity of car = aThan a vector = ai = 20i (given)

Let velocity of car = aThan a vector = ai = 20i (given)Where i is unit vector along east word direction

Let velocity of car = aThan a vector = ai = 20i (given)Where i is unit vector along east word directionAnd let velocity of bus is = b vect

Let velocity of car = aThan a vector = ai = 20i (given)Where i is unit vector along east word directionAnd let velocity of bus is = b vectSo b vec - a vec = 20root3 j

Let velocity of car = aThan a vector = ai = 20i (given)Where i is unit vector along east word directionAnd let velocity of bus is = b vectSo b vec - a vec = 20root3 j(given, here j because it's along North which is y asis)

Let velocity of car = aThan a vector = ai = 20i (given)Where i is unit vector along east word directionAnd let velocity of bus is = b vectSo b vec - a vec = 20root3 j(given, here j because it's along North which is y asis)So b = 20root 3 j +20i

Let velocity of car = aThan a vector = ai = 20i (given)Where i is unit vector along east word directionAnd let velocity of bus is = b vectSo b vec - a vec = 20root3 j(given, here j because it's along North which is y asis)So b = 20root 3 j +20iMode of b = root ( 20*20*3 + 20*20) =root 1600 = 40 m/s

Let velocity of car = aThan a vector = ai = 20i (given)Where i is unit vector along east word directionAnd let velocity of bus is = b vectSo b vec - a vec = 20root3 j(given, here j because it's along North which is y asis)So b = 20root 3 j +20iMode of b = root ( 20*20*3 + 20*20) =root 1600 = 40 m/sAnd tan theta = 20root3/20=root 3

Let velocity of car = aThan a vector = ai = 20i (given)Where i is unit vector along east word directionAnd let velocity of bus is = b vectSo b vec - a vec = 20root3 j(given, here j because it's along North which is y asis)So b = 20root 3 j +20iMode of b = root ( 20*20*3 + 20*20) =root 1600 = 40 m/sAnd tan theta = 20root3/20=root 3Hence angle = 60 degree towards East to north
