Explainin a short setence why you don't know if the dog's final position is - 4m or + 6m. 3.3. a. The dog seen below moves with velocity v = 1.5 % Put a number in the first blank and a word in the second: It's speed is m/s and its direction is . Assume the standard orientation of the axis where postive is the right. b. Suppose also that a cat moves with velocity v = 3.0 % Draw the velocity vector on each animal below and comment on the drawing scale: i.e., how much longer is the cat's velocity vector compared to the dogs? S \"-\\ 3 - 3 = W 4.4, A quick way to see if a variable n represents a vector component or a scalar is to add the phrase \"in the direction east\" and see if that sentence makes sense. Do that to each below and state if the variable represents a scalar or vector a. A force of F = 10 lbs was applied to the brick b. Juan drank V = 2 Liters of Pepsi. 5.C. B > _ feet -10 o 10 20 30 40 S50 The jogger moves from point A to point B. Assume distance units of feet [ft] a. Onan axes with no numbers you will often see a + and/or symbol at the end of the axis like > What purpose does the + sign serve? Explain in a short sentence. HELP: See problem 2.2a,b. b. In the diagram above, what is the jogger's initial position? c. What is the jogger's final position? d. What is his displacement? e. What distance did he move? f. Draw both position vectors and the displacement vector in the picture above. HELP: the displacement vector has its tail at the initial position and tip at the final position. 6.C. a. Some quantities in physics are not just numbers but are considered a geometric arrow (having both a size and direction). These quantities are called Q Notifications 3:02AM Sat Mar 9 eee = 80% (@ ) 2ag HCHW Ch 2 (31).pdf Q M b. Physics quantities that are not arrows (i.e., don't have a direction) are called .
