1 WYSE caemic Challenge Sectinal Physics 7 Slutin Set. Crrect answer: E. Energy has imensins f frce times istance. Since respnse e. has imensins f frce ivie by istance, it clearly es nt represent energy. Dimensins fr each respnse are wrke ut belw using the fllwing efinitins: [P] pwer, [E] energy, [t] time, [F] frce, [M] mass, [a] acceleratin, an [] istance. a. watt ay [P]x[t] [E]/[t]x[t] [E] b. ft puns []x[f] [E] c. kg m /s [M] x [] x [] / [t] / [t] [M] x { [] / [t] } x [] [M] x [a] x [] [F] x [] [E].

Frictin is an example f a nn-cnservative frce since the wrk ne by frictin is nt etermine by the starting an ening psitin, but by the path taken between the starting an ening psitin. 4. Crrect answer: E. Since n external impulse acts upn the system, the ttal mmentum f the system must be cnstant. Hwever the bjects in the system may exchange mmentum as they cllie. Thus if ne f the bjects gains mmentum thrugh the cllisin, the ther bject in the system must lse the same amunt f mmentum. Since the cllisin is perfectly elastic, the ttal kinetic energy f the system must be cnstant. Hwever the bjects in the system may exchange kinetic energy as they cllie. Thus if ne f the bjects gains kinetic energy thrugh the cllisin, the ther bject in the system must lse the same amunt f kinetic energy. 5. Crrect answer: D. ω v / r (6.8 m / s) / (.33 m) 8. ra/s 6. Crrect answer: C. t any instant, the tire appears t be rtating abut the pint in cntact with the highway. Since the tp f the tire is a istance r frm the cntact pint, the linear spee f the tp f the tire is v (r) ω (.66 m) (8. ra/s) 53.6 m/s 7 Sectinal Slutin Set

Frce (N) x (m) W ½ (5 N + N) (5. m 3. m) 5 N m 5 J 9. Crrect answer: B. Cnsiering the chil+earth system, frictin is an external frce acting n the system which will change the energy f the system. et W the wrk ne by frictin, ΔKE the change in kinetic energy, an ΔGPE the change in gravitatinal ptential energy. W ΔKE + ΔGPE ½ (9. kg) (.3 m/s) + (9. kg) (9.8 m/s ) (-.5 m) -449 J. Crrect answer: D. The sum f frces in the vertical irectin equals zer. F sin(33. ) W + N F sin(33. ) (9. kg)(9.8 m/s ) + (5 N) F 6.8 N 33. F W N. Crrect answer: C. ccring t Newtn s n aw, the irectin f the acceleratin must be in the irectin f the frce, which is in a irectin twar the center f the earth. Even thugh the satellite is mving at cnstant spee, since it is mving in a circular rbit, an thus changing irectin, it experiences a change in velcity an is therefre accelerating. 7 Sectinal Slutin Set

Crrect answer:. Using Newtn s n aw: a F / M sys. N / (7. kg + 3. kg).5 m/s 4. Crrect answer: E. et wn be in the irectin f the negative y axis, with y at the surface f the table. et Viy the initial y cmpnent f velcity, V fy the final y cmpnent f velcity, a y the y cmpnent f acceleratin, y the final y psitin, an y the initial y psitin. f Then, V fy Viy + ay ( y f yi ) + ( 9.8m / s )(.5m ). Thus V fy 5.4m/ s. Since the marble still has an x cmpnent f velcity equal t 4. m/s, use the Pythagrean Therem t fin the final spee. S, V f fx fy / V + V m / s 6.74m s. 5. Crrect answer: C. The current in each element f the series circuit will be I V / tt (. V) / (. Ω Ω).5. The pwer issipate in the 47. Ω resistr will be P I (.5 ) (47. Ω).938 W. The energy issipate in the 47.
