Chapter B - Problems Blinn College - Physics 2425 - Terry Honan Problem B.1 x H m L t H s L 2 3 7 2 4 8 (a) What is the average velocity between 0 s and 2 s, between 3 s and 7 s, between 2 s and 7 s? (b) What is the instantaneous velocity at 1 s and and at 4 s? (c) What is the average acceleration between 1 s and 4 s? (b) What is the instantaneous acceleration at 1 s and at 4 s? Problem B.2 A particle moves in one dimension. It's position as a function of time is given, in SI units, by: x H t L = 2 t 4 - 5 t 2 + 18. (a) What is the average velocity between 2s and 4s? (b) What is the instantaneous velocity at 3s? (c) What is the average acceleration between 2s and 4s? (d) What is the instantaneous acceleration at 3s? Problem B.3 x t t 1 t 2 t 3 t 4 The above diagram is a graph of position versus time. For t < t 1 the graph is a straight line. For t > t 4 the graph is a horizontal line. I
