Detailed explanation-1: -Answer: The displacement is 12 km North. Explanation: Here, we are going to solve for the displacement of a hiker. Given information. xi = 9.0 km north (+) Solving the problem. Displacement = 12km.
Detailed explanation-2: -AI Recommended Answer: 9.0 + 3.0 = 12.0 km.
Detailed explanation-3: -Explanation: Let’s start with the hiker’s displacemnt, which is simply the distance between its starting point and its finish point. Displacement does not take into account the path taken from start to finish, it just deals with the shortest distance between these two points.
Detailed explanation-4: -The route followed by a hiker consists of three displacement vectors →A, →B, and →C . Vector →A is along a measured trail and is 1550 m in a direction 25.0∘ north of east. Vector →B is not along a measured trail, but the hiker uses a compass and knows that the direction is 41.0∘ east of south.
