Spring 2010 Homework Assignment Page 1 for PH111L (Fundamentals of Physics I)

Text: Serway & Jewett Physics for Scientists and Engineers (8th edition)

OQ are 'objective questions'. Be prepared to discuss them in class but no need to put answers on paper.
CQ are 'conceptual questions'. Put your responses on paper in coherent elegant prose, using a few full sentences.
P are 'problems'. The answers to the odd-numbered problems are in the back of the book. Put your solutions on paper.

Assignment 1 (Assgd Tues 2 Feb; Due Thurs 11 Feb)

CH 1 OQ #3, 4; P #10, 14, 18, 23

CH 2 OQ #5, 6, 7, 12, 15; P #3, 4, 5, 6, 10, 14, 22, 25

Assignment 2 (Assgd Thurs 11 Feb; Due Thurs 18 Feb)

CH 2 OQ #16; P #38, 46, 50, 68

CH 3 OQ #2, 5, 6, 9, 13; P #2, 7, 10 ["Graphically" means to use ruler and protractor to accurately DRAW a picture and to measure magnitude and direction of the resultant. If you need to borrow a protractor and or ruler please ask], 16, 20, 25, 26 [note that here you have a "tilted" coordinate system, so define your directions with care], 29 [mule-pulling is a classic force vector scenario...], 31, 32

Assignment 3 (Assgd Thurs 18 Feb; Due Thurs 25 Feb)

CH 4 OQ #2, 4; P #3, 6, 11, 12, 15, 24

Assignment 4 (Assgd Thurs 25 Feb; Due Thurs 4 Mar)

CH 4 OQ #1, 9,13; P #28, 29, 32, 33 (making figures would probably help), 37 [hints: the "fixed" frame is the ground; the "moving" frame is the air; so, in (a), the moving frame moves at 35 km/hr due south; use unit vector notation, with i along E and j along N; work in km/hr], 40 (a very interesting little problem, even in 1d, 44 (optional but a nice review problem on vectors)

Assignment 5 (Assgd Thurs 4 Mar; Due Tues 16 Mar)

CH 5 OQ #3 (use F = ma), 5, 8; P #2, 6, 8, 10, 13, 14, 15, 18 (classic!), 20 (super-classic - for (d) you may use the result from the notes, which you can thus review), 21 (oh my, another classic!), 31

Assignment 6 (Assgd Thurs 18 Mar; Due Tues 6 Apr)

CH 5 OQ #9, 10, 13; CQ #2, 6, 11, 19, P #30, 33, 38, 39, 43 (see Ex 5.11), 48

CH 6 OQ #4, 5; CQ #5, 10; P #2, 4, 8, 9

Assignment 6 part II (Assgd Thurs 1 Apr; Due Thurs 6 Apr)

CH 6 CQ #7, 10; P #13, 14, 19 [the loop is better described as an "upside-down" teardrop; but even, then, when drops are falling they look more like m&ms than elongated objects], 26, 29, 32 [not as complicated as it sounds, and a nice of ideas of friction and drag]
