Physics 111.01 Fall, 2008 Solutions, Problem Set 1c (2) HW 1c # 1 = Multiple-Choice Problem. For the following multiple-choice question, what must be the correct answer? (Assume there is no error in the question, i.e. the correct answer is among the choices. You also know enough to know that [x]=m, [v]=m/s, and [a]=m/s 2 .) Question: Bob bla bla bla bla x bla bla bla bla t bla bla bla bla v bla bla bla bla a bla bla. What is the correct expression for how fast Bob is traveling at this moment? t(3ax) 1/2 6axt/v x 2 /(5t 2 v) vat 3 For each case, put in units for the variables and cancel. The correct result will give the units of velocity, [m]/[s]. As an example look at the first expression. () [] 1/2 1/2 2 1/2 22 mm m 3[ ] [ ] [ m ] [ ] [ ] [ ] s ss ta x s s s m ⎛⎞ −−> = = = ⎜⎟ ⎢⎥ ⎝⎠ Meters is not the units of velocity, so this one is wrong. HW 1c # 2 = Golfer Problem. The golfer in figure 2-26 sinks the ball in two putts as shown, where d 1 = [12] m and d 2 = [2.6] m.
