Take your time. Show your thinking.
1. On a speed-time graph, a train accelerates uniformly from rest to 42 m/s in 8 s and then continues at a constant speed of 42 m/s for a further 15 s. Calculate the total distance travelled.

v_max = 34 m/s (t₁ = 8 s, t₂ = 11 s) · Distance = Area = ½vt₁ + vt₂ 6. On a speed-time graph, a train accelerates uniformly from rest to 40 m/s in 5 s and then continues at a constant speed of 40 m/s for a further 5 s. Calculate the total distance travelled.
v_max = 40 m/s (t₁ = 5 s, t₂ = 5 s) · Distance = Area = ½vt₁ + vt₂ 7. On a speed-time graph, a train accelerates uniformly from rest to 44 m/s in 3 s and then continues at a constant speed of 44 m/s for a further 11 s. Calculate the total distance travelled.
v_max = 44 m/s (t₁ = 3 s, t₂ = 11 s) · Distance = Area = ½vt₁ + vt₂ 8. On a speed-time graph, a train accelerates uniformly from rest to 20 m/s in 10 s and then continues at a constant speed of 20 m/s for a further 7 s. Calculate the total distance travelled.
v_max = 20 m/s (t₁ = 10 s, t₂ = 7 s) · Distance = Area = ½vt₁ + vt₂ 9. On a speed-time graph, a train accelerates uniformly from rest to 8 m/s in 7 s and then continues at a constant speed of 8 m/s for a further 12 s. Calculate the total distance travelled.
v_max = 8 m/s (t₁ = 7 s, t₂ = 12 s) · Distance = Area = ½vt₁ + vt₂ 10. On a speed-time graph, a train accelerates uniformly from rest to 38 m/s in 10 s and then continues at a constant speed of 38 m/s for a further 18 s. Calculate the total distance travelled.
v_max = 38 m/s (t₁ = 10 s, t₂ = 18 s) · Distance = Area = ½vt₁ + vt₂ 11. On a speed-time graph, a train accelerates uniformly from rest to 38 m/s in 6 s and then continues at a constant speed of 38 m/s for a further 17 s. Calculate the total distance travelled.
v_max = 38 m/s (t₁ = 6 s, t₂ = 17 s) · Distance = Area = ½vt₁ + vt₂ 12. On a speed-time graph, a train accelerates uniformly from rest to 14 m/s in 3 s and then continues at a constant speed of 14 m/s for a further 11 s. Calculate the total distance travelled.
