Typos in Touger, 1^st Ed

p.31 Fig. 2-21 Graph (b) is v vs. t   (NOT y vs. t)

p.40, problem 2-11  Answers to parts c and d are mixed up in back of book

p.63, Example 3-3.  Last paragraph should begin: "To find theta, first key in -2.69, then press.."  (In text, the number is written incorrectly.)

p.64, Fig.3-26, part (b). B_x and B_y are reversed!

p.69, Example 3-6. "Because Equations 3-12x and 3-12y…"  These equations do not exist.

p.71, Example 3-7, about 1/3 way down from top of page. a_y_bar is +2.5 m/s^2 (the answer is positive, not negative)

p.71 Error: Bottom of page, last sentence.  Instantaneous values of ax and ay at point P are NOT equal to the average values of ax, ay over the trip from C to D. (Text claims they are equal.)

p.72. Near bottom of page. Table with column heading "horizontal motion": 2^nd and 3^rd line under that column heading should read vx = vox,  vx2 = vox2 (not vx – vox, etc)

p.101, Fig 4-8 Equation under figure mixes vector and scalar quantities ( a vector cannot equal a scalar!)

p.103, Example 4-3. Last equation in the example, near middle of page should read mA = FonAbyB / aA  (acceleration is aA, NOT aB)

p.116, near bottom of page. Sentence "Newton's second law remains an unusable abstraction… on the left side of Equation 4-5."  The equation referred to is Equation 4-8, NOT 4-5.

p.123,  6^th line from top: Should read "Find the upward acceleration of the block." (not of the rope)

p.123, about ¾ of way down the page. vy = voy +ay*deltaT = … = 0.40 m/s  (units are m/s NOT s)

p.128, Example 5-6.  The angles theta(q) and phi (f) are mixed up between the diagram and the text.

p.133, middle of page.  "a. Putting these specifics into equations 4-8z and 4-8y, .."  The equations 4-8x and 4-8y are on page 125, in Chap.5 (not in Chap.4).

p.135 Fig.5-21. The distance d1=3 m is from x = 2 to x = 5 (NOT from x=0 to x=5 as in the diagram).

p.156, Fig.6-2. Part (d). The last figure on the right shows the little man having caught the chair, in which case the KE would be zero. The figure should show the chair about to hit the ground, in which case it would have maximum KE and minimum PE, which is what the figure intended to show.

p.163 Fig 6-12 at top of page. Part (d) In this example, the phrase "total force" should read "total force exerted by the two movers". The real "total force" would include the normal force and the force of gravity.

p.166,167, Case 6-3. Signs are reversed throughout. In every example given, the Dy = y_final – y_initial should be negative (not positive). Since Dy is negative in these examples, DPE = mg Dy is also negative.

P.169, Case 6-4. The force diagram is so messed up and the text is so confusing, I recommend that you do not even read this.
