Question

If a person traveled from Sacramento to Los Angeles by car, their distance would be 384.9 miles. What would their displacement be? _____________________ If that same person returned to Sacramento from Los Angeles by the same route in the same car, what would the total round trip distance be? 400 miles What would their total displacement be? _____________________

Answer 1

Displacement from Sacramento to Los Angeles is 384.9 miles

Total path length is given as 769.8 miles

Displacement of complete round trip is ZERO

Step-by-step explanation:

As we know that the displacement is the change in the position from initial to final in a straight line

Here we know that the car travel from Sacramento to Los Angeles

So the straight line distance between two is the displacement

so we have

displacement = 384.9 miles

Now we know that he returns from Los Angeles to Sacramento by same path

So total distance moved by it is same as total path length

d = 384.9 + 384.9

d = 769.8 miles

Also we know that initial and final positions are same so displacement is ZERO for complete round trip.
