Physical Sciences/P1 7 CAPS-Grade 10 DBE/November 2016 QUESTION 2 (Start on a new page.) An impatient businessman paces up and down while making a business call on his cellphone. C A B N E S He starts at his desk and walks 5 m east (from A to B) and then walks 7 m west (from B to C). This process takes him 20 s. 2.1 Use a vector scale diagram and represent the two displacements of the man (from A to B AND from B to C). Label ALL the vectors clearly and write down the displacements next to the vectors. Use a scale of 1 cm representing 1 m for your diagram. (2) 2.2 What is the businessman's change in position at C relative to A? 2.3 Calculate the total distance the man covers. 88 (2) (2) 2.4 Explain why the value calculated in QUESTION 2.2 differs from the one calculated in QUESTION 2.3. (2) 2.5 Define the term velocity. (2) 2.6 Calculate the man's average velocity. (4) [14]

P3C A hiker takes a three - part journey as described in map coordinates below. Determine the hiker's displacement after the three - part hike. Record your answer in polar coordinates with magnitude and the direction measured relative to the positive - x axis in the spaces below. Use units for the magnitude, but do not use the degree unit on direction.Part 1) 1600 m at 40.00 East of North.Part 2) 1800 m at 20.00 North of West.Part 3) 1200 m due North.
