Qu.s involving successive time intervals or successive distances

Qu.s involving successive time intervals or successive distances Ex. A car accelerates at a constant rate. It passes 3 posts A, B and C separated by 50m. A to B takes 10s and B to C takes 8s Find the acceleration We are not told the starting velocity so use u = starting velocity

  1. Qu.s involving successive time intervals or successive distances Ex. A car accelerates at a constant rate. It passes 3 posts A, B and C separated by 50m. A to B takes 10s and B to C takes 8s Find the acceleration We are not told the starting velocity so use u = starting velocity For stage 1 A to B For stage 1 and 2 combined A to C Note that the starting velocity for AB and for AC is the same. Using s = ut + at2 stage AB 50 = 10u + a102 50 = 10u + 50a stage AC 100 = 18u + a182 100 = 18u + 162a Solving simultaneously u = 4.3m/s and a = 0.139m/s2 10s 18s A B C • u = ? s = 50 t = 10s and a = ? u = ? s = 100 t = 18s and a = ?
