These questions are to be answered with a short paragraph. You will be graded on the physics content of your answer as well as on its structure and conciseness. Remember, as with everything, neatness counts.

1. Is it possible for a slowing car to have a positive acceleration? Explain? 2. P and Q shown below are two vectors of equal length (magnitude) but different direction. Which vector shows the sum P 9? (Support your choice with a complete diagram)

Explanation / Answer

(1)

yes, The car moves to the left (negative velocity), but accelerate to the right (positive acceleration), so the car moves to the left and slow down.

(2)

the vector addition of vector p and q shows vector c
