Answer to Question #169662 in Physics for Lisa

Question

A dog initially at a position 2.8 m [W] of its owner, runs to retrieve a stick that is 12.6 m [E] of its owner.

1. Draw a diagram showing the position and displacement vectors in this situation.
2. Determine the displacement the dog needs to reach the stick. 

15.4 m [E]

5. Table 1 gives the position-time data of a ball that has left a bowler’s hand and is rolling forward.  Determine the displacement between the following times:

Table 1

1. t = 0 s and t = 1.0 s
2. t = 1.0 s and t = 2.0 s
3. t = 1.0 s and t = 3.0 s

Answer 1

1)

2)

$$S_{sd}=12.6+2.8=15.4\ m \ E$$
