Multiple-choice questions may continue on the next column or page find all choices before answering. 001 10.0 points Consider position [ x ] = L, time [ t ] = T, ve- locity [ v ] = L / T and acceleration [ a ] = L / T 2 . Find the exponent A in the equation v = a 2 t A x 1. 2 2. 1 3. 4 4. 3 correct Explanation: [ v ] = [ a ] 2 [ t ] A [ x ] L T = parenleftbigg L T 2 parenrightbigg 2 T A L = L 2 L T A- 4 Equating exponents, A- 4 =- 1 A = 3 . 002 (part 1 of 2) 10.0 points A physics book is moved once around the perimeter of a table of dimensions 1 m by 3 m. If the book ends up at its initial position, what is the magnitude of its displacement? 1. None of these 2. 0 m correct 3. 8 m 4. 2 m 5. 3 m 6. 6 m 7. 7 m 8. 5 m 9. 4 m 10. 1 m Explanation: Since its final position is the same as its initial position, the displacement is 0. 003 (part 2 of 2) 10.0 points What is the distance traveled?...
