Finding Displacement Using Vectors
Kevin brings his dog to a park. He throws two balls for his dog to catch. The path of the first ball is described by the vector v1=130i+10j and that of the second ball is described by the vector v2=80i+(−40)j where the distances are all expressed in meters.
Evaluating Velocity Using Vectors
Elaine can swim in still water (no current) with a speed of 5 m/s. She now goes swimming in a river which has a current flowing towards west with a speed of 2 m/s. Assuming her speed is the same,
Determining Displacement and Velocity Using Vectors
A plane is travelling south with a speed of 140 km/h. Simultaneously, there is a steady wind blowing due west with a speed of 40 km/h.
