Acar travels 1.46 km in the x-direction, then turns left 74.8 ◦ to the original direction and travels an additional distance of 2.57 km. calculate the x component of the car's net displacement.

 The x component of the car's net displacement = 3.94 km

Explanation:

   A car travels 1.46 km in the x-direction, which means displacement = 1.46 i km.

  Then car turns left 74.8⁰ to the original direction and travels an additional distance of 2.57 km, which means displacement = 2.57 cos 74.8⁰ i +2.57 sin 74.8⁰ = (2.48 i + 0.67 j) km

  So total displacement = 1.46 i + 2.48 i + 0.67 j = (3.94 i + 0.67 j) km

  The x component of the car's net displacement = 3.94 km

with the invention of the automobile, the woman of the house could drive to the store and get groceries. women were also free to socialize more. during world war ii women were allowed to work in factories to the war effort and could drive to work or ride mass transit buses to their jobs.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
