1.A person is following a set of directions. He has to walk 2km2km east and then 1km1km north. He takes a wrong turn and walks south instead of north for the second leg of the trip. The magnitude of his total displacement will be the same as it would have been had he followed directions correctly. - TRUE OR FALSE
2. A person attempts to cross a river in a straight line by navigating a boat at 15m/s15m/s. If the river flows at 5.0m/s5.0m/s from his left to right, what would be the magnitude of the boat’s resultant velocity? In what direction would the boat go, relative to the straight line across it?
