Q M @ SOLUTIONS : Period Score /10 Skill Builder: Topic 4.2 - Straight-Line Motion: Connecting Position, Velocity and Acceleration — Two Truths &A Lie Is Straight Line Motion bugging you? Five different bugs are are moving along the x axis. The graphs of their velocitics are given below on various time intervals. There are three statements below each velocity graph. Two of these statements are true while one statement is false. For each velocity graph: 1. Tdentify which of the three statements is false 2. Explain why the statement is false and/or correct the statement. Bug #1 - Herman Statement 1: a(4) =0 Statement 2: a(11) <0 Statement 3: a(13) < 0 a(13) <0 a(13) >0 because v(r) is increasing at f = 13 Particle 2 - Brutus ) s Statement 1: The particle changes directionsat t = 4 The particle does not change directions at 1 = 6 because Statement 2: The particle changes directionsatt = 6 r(l) e Statement 3: The particle is moving leftat t = 2 Bug #3 - Landon 5 v(t) Statement 1: The particle is slowing down at t = 4 The particle is speeding up at =6 because Statement 2: The particle is slowing downatt = 6 v(r) <0and a(t) = v’(t) <0 Statement 3: The particle is slowing downatt =8 Bug #4 - Hershel
