Question
1. What is the difference between speed and velocity? a. Speed is an average quantity while velocity is not. b. Velocity containsinformation about the direction of motion while speed doesnot. c. Speed is measured in mph, while velocity is measure inm/s. d. The concept of speed applies only to objects that areneither speeding up or slowing down, while velocity applies toevery kind of motion. e. Speed is used to measure how fast an object is moving in astraight line, while velocity is used for objects moving alongcurved paths. 2. The quantity 2.67 x 10^3 has how many significantfigures? a.1 b.2 c.3 d.4 e.5 3. If Libby walks 100 m to the right, then 200 m to the left,her net displacement vector points a. to the right. b. to theleft. c. has zero length. d. cannot tell without more information. 4. Velocity vectors point a. in the samedirection as displacement vectors. b. in the opposite direction as displacement vectors. c. perpendicular to displacement vectors. d. in the same direction as acceleration vectors. e. velocity is not represented by a vector. Hi, so the answers highlighted in yellow are my "answers" canyou please provide me with the correct solutions to everythingso I can see what I need to work on. Thanks. 1.

It seems that you have everything correct. Are you usingwebassign or some confangled contraption to grade your answer, oris this in the book. It seems you know that: 1. Speed is scalar whereas velocity is vector. 2. Significant figures in a number with decimals and scientificnotation. 3. How to do 1-dimensional vector addition. 4. That velocity can not disagree with displacement indirection. I don't see any problems...
