These sample questions are meant to give you practice with some extra probles There is NO guarantee that similar type of questions will appear in the exam. The samples provided here are not exhaustive lists of questions for any relevant chapter or topic. 1) A rectangular garden measures 15 m long and 13.70 m wide. What is the length of a diagonal from one corner of the garden to the other? A) 18 m B) 19 m C) 20 m 2) A certain CD-ROM disk can store 600 megabytes of information. If an average word requires 9.0 bytes of storage, how many words can be stored on one disk? A) 6.7 × 107 words B) 5.4 x 109 words C) 2.1 x 107 words D) 2.0% 1 09 words 3) Consider a deer that runs from point A to point B. The distance the deer runs can boe greater than the magnitude of its displacement, but the magnitude of the displacement can never be greater than the distance it runs. A) True B) False 4) You drive 6.0 km at 50 km/h and then another 6.0 km at 90 km/h. Your average speed over the 12 km drive will be A) greater than 70 km/h. B) equal to 70 km/h. C) less than 70 km/h. D) exactly 38 km/h. E) It cannot be determined from the information given because we must also know directions traveled 5) Which of the following situations is impossible? A) An object has velocity directed east and acceleration directed west. B) An object has velocity directed east and acceleration directed east. C) An object has zero velocity but non-zero acceleration. D) An object has constant non-zero acceleration and changing velocity. E) An object has constant non-zero velocity and changing acceleration. 6) Suppose that a car traveling to the east (+x direction) begins to slow down as it approaches a traffic light. Which statement concerning its acceleration must be correct?

Explanation / Answer

1. Diagonal = (13.72+ 152)0.5 = 20.314 m

2. Number of words can be stored = total size / size of each word = 600 x 106/ 9 = 6.7 x 107

3. True. Because distance >= displacement.

4. Av speed = 2 a b /(a+b)

a= 50 km/h

b= 90 km/h

Av speed = 2 x 50 x 90 / ( 50+90) = 64.285 km/h
