Take your time. Show your thinking.
1. On a speed-time graph, a train accelerates uniformly from rest to 42 m/s in 2 s and then continues at a constant speed of 42 m/s for a further 19 s. Calculate the total distance travelled.

v_max = 32 m/s (t₁ = 12 s, t₂ = 11 s) · Distance = Area = ½vt₁ + vt₂ 6. On a speed-time graph, a train accelerates uniformly from rest to 18 m/s in 2 s and then continues at a constant speed of 18 m/s for a further 5 s. Calculate the total distance travelled.
v_max = 18 m/s (t₁ = 2 s, t₂ = 5 s) · Distance = Area = ½vt₁ + vt₂ 7. On a speed-time graph, a train accelerates uniformly from rest to 22 m/s in 6 s and then continues at a constant speed of 22 m/s for a further 9 s. Calculate the total distance travelled.
v_max = 22 m/s (t₁ = 6 s, t₂ = 9 s) · Distance = Area = ½vt₁ + vt₂ 8. On a speed-time graph, a train accelerates uniformly from rest to 44 m/s in 2 s and then continues at a constant speed of 44 m/s for a further 13 s. Calculate the total distance travelled.
v_max = 44 m/s (t₁ = 2 s, t₂ = 13 s) · Distance = Area = ½vt₁ + vt₂ 9. On a speed-time graph, a train accelerates uniformly from rest to 28 m/s in 11 s and then continues at a constant speed of 28 m/s for a further 9 s. Calculate the total distance travelled.
v_max = 28 m/s (t₁ = 11 s, t₂ = 9 s) · Distance = Area = ½vt₁ + vt₂ 10. On a speed-time graph, a train accelerates uniformly from rest to 24 m/s in 6 s and then continues at a constant speed of 24 m/s for a further 9 s. Calculate the total distance travelled.
v_max = 24 m/s (t₁ = 6 s, t₂ = 9 s) · Distance = Area = ½vt₁ + vt₂ 11. On a speed-time graph, a train accelerates uniformly from rest to 34 m/s in 8 s and then continues at a constant speed of 34 m/s for a further 15 s. Calculate the total distance travelled.
v_max = 34 m/s (t₁ = 8 s, t₂ = 15 s) · Distance = Area = ½vt₁ + vt₂ 12. On a speed-time graph, a train accelerates uniformly from rest to 38 m/s in 3 s and then continues at a constant speed of 38 m/s for a further 12 s. Calculate the total distance travelled.
v_max = 38 m/s (t₁ = 3 s, t₂ = 12 s) · Distance = Area = ½vt₁ + vt₂
