Acar climbs 10.0 kilometers up a hill that inclines 8.0 degrees. what is the car's vertical displacement?

The correct answer to the question is :

CALCULATION:

The angle of inclination of the hill with the horizontal ground .

The magnitude of displacement  or the distance travelled by the car up that hill is given as -

                        distance S = 10.0 Km.

We are asked to calculate the vertical displacement.

Applying vector resolution process, we get-

(a) is the horizontal component

 (b) is the vertical component.

Hence, the vertical displacement is calculated as -

                        Vertical displacement

                                                                    = 1.392 Km.

Hence, the vertical displacement of the car is  

explanation:

newton's third law, for every action there is an equal and opposite reaction.

okay i have so many questions. but the big one here is: um wt..f is this mess? ?
