Part AFind the x- and y-components of the vector d⃗ = (4.0 km , 29 ∘ left of +y-axis).Express your answer using two significant figures. Enter the x and y components of the vector separated by a comma. d⃗ = km Part BFind the x- and y-components of the vector v⃗ = (2.0 cm/s , −x-direction).Express your answer using two significant figures. Enter the x and y components of the vector separated by a comma. v⃗ = cm/s Part CFind the x- and y-components of the vector a⃗ = (13 m/s2 , 36 ∘ left of −y-axis).Express your answer using two significant figures. Enter the x and y components of the vector separated by a comma. a⃗ x = m/s2

Solution :

Part A .

Given : The and components of the vector, d = degree left of -axis.

So the component is = -4 x sin (29°) = -1.939 km

            component is = 4 x cos (29°) = 3.498 km

Part B

Given : The and components of the vector, ,

So the component is = -2 cm/s

            component is = 0

Part C

Given : The and components of the vector, left of -axis.

So the component is = -13 x sin (36°) = -7.6412

            component is = -13 x cos (36°) = -10.517

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.
