Scalars and Vectors: Graphical Addition — Homework
Draw a quick sketch of each vector pair before computing a resultant.
- 1.Two forces act on an object: 5 N east and 12 N north. Find the magnitude of the resultant.
- 2.A displacement of 9 m south is added to a displacement of 12 m south. Find the resultant.
- 3.A boat moves at 8 m/s east while the current pushes it 6 m/s north. Find the magnitude of the resultant velocity.
- 4.Explain why "20 mph" is a scalar but "20 mph north" is a vector.
- 5.For the boat problem above, describe the general direction of the resultant relative to east (you do not need the exact angle).
- 6.Describe a real scenario with two vectors that are neither parallel nor perpendicular (for example, two ropes pulling a sled at different angles), and explain how you would approach finding their resultant.
