John walks 180 km north then turns right and walks 180 km, Ask an Expert

Academics

John walks 1.80 km north, then turns right and walks 1.80 km east. His speed is 2.00 m/s during the entire stroll.

Part A: What is the magnitude of his displacement, from beginning to end?

Part B: If Jane starts at the same time and place as John, but walks in a straight line to the endpoint of John's stroll, at what speed should she walk if she wants to arrive at the endpoint just when John does?
