The car moved along the ring road around Moscow and drove along it twice. What are the path and displacement if the length of the ring road is 400m.
L1 = 400 m.
n = 2.
S -?
L -?
The movement of the body S is a vector that connects the initial and final position of the body. Since the car has passed n = 2 whole rings, its initial and final positions are the same. Therefore, the movement of the car is S = 0.
The distance traveled L is the length of the line that the body describes when moving.
L = n * L1.
L = 2 * 400 m = 800 m.
Answer: displacement S = 0, path L = 800 m.
