5. Example: Resultant Displacement Spider-man walks 9.0 m horizontally until he hits a wall. He then decides to climb up a building for 3.0 m. What is his resultant displacement?

6. Steps 1)Define Spider-man walks 9.0 m horizontally until he hits a wall. He then decides to climb up a building for 3.0 m. What is his resultant displacement?

7. Choose an equation: Rearrange the equation to isolate the unknown: 2)Plan Trig Review

8. Substitute the values into the equation and solve 3)Calculate

9. 4)Evaluate Resultant displacement needs both value and direction. In this case, Spider-man’s resultant displacement is 9.5 meters and 18 ° above the horizontal. Warm-Up Video Answer
