Answer:
because of the raindrop velocity relative of the car has a vertical and horizontal component
Explanation:
- The car moves in a <em>horizontal direction </em>relative to the ground. The raindrops fall in the <em>vertical direction</em> relative to the ground.
- Their velocity relative to the moving car has both vertical and horizontal components and this is the reason for the diagonal streaks on the side window.
-
The diagonal streaks on the windshield arise from a different reason.
-
The drops are pushed off to one side of the windshield because of air resistance.
