In the afternoon, Adam rides his bike from his home to the mall to pick up a job application. Then he rides back home to take a nap. What is the magnitude of his displacement (in meters)? *The distance from his home to the mall is 1100m*

The magnitude of Adam's displacement is 0 m

Explanation:

Given;

Adam's distance from his home to the mall, d₁ = 1100m

then, his distance from the mall back to his home, d₂ = 1100m

Adam's displacement is given by;

Displacement = final position - initial position

Adam's displacement = d₂ - d₁

Adam's displacement = 1100 m - 1100 m = 0 m

Therefore, the magnitude of Adam's displacement is 0 m

the total distance traveled by the car is

30km + 49km = 79 km .
