if a car moves 12km North, 19km East, and 12km South, a) Find the total distance covered.

b) Find the car's displacement.

net North is zero.

distance=12+19+12
displacement=19E

19

a. distance = 12 + 19 + 12 = 43 km.

b. Disp. = 12i + 19 - 12i = 19 km, East.

The distance you will add up all of the "space" covered.

For the displacement i don't know...sorry

To find the total distance covered by the car, we need to calculate the sum of the distances traveled in each direction.

a) Total distance covered:
- Distance traveled North: 12 km
- Distance traveled East: 19 km
- Distance traveled South: 12 km

To find the total distance, add the distances traveled in each direction:
12 km + 19 km + 12 km = 43 km

Therefore, the total distance covered by the car is 43 km.

b) To find the car's displacement, we need to identify the net change in position from the starting point to the final position. Displacement is a vector quantity, meaning it has both magnitude and direction.

In this case, the car's starting position is the same as the ending position since it traveled North and then South. The car's displacement is only influenced by the distance traveled East.

To find the displacement, we can use the Pythagorean theorem. The distance traveled North and South will cancel each other out when calculating displacement.

- Distance traveled North: 12 km
- Distance traveled South: 12 km

Since these distances are equal and opposite, they result in zero displacement in the North-South direction.

The distance traveled East is 19 km, so the displacement in the East direction is simply 19 km.

Therefore, the car's displacement is 19 km to the East.
