v_max = 44 m/s (t₁ = 3 s, t₂ = 17 s) · Distance = Area = ½vt₁ + vt₂ 7. On a speed-time graph, a train accelerates uniformly from rest to 26 m/s in 11 s and then continues at a constant speed of 26 m/s for a further 7 s. Calculate the total distance travelled.
v_max = 26 m/s (t₁ = 11 s, t₂ = 7 s) · Distance = Area = ½vt₁ + vt₂ 8. On a speed-time graph, a train accelerates uniformly from rest to 12 m/s in 4 s and then continues at a constant speed of 12 m/s for a further 15 s. Calculate the total distance travelled.
v_max = 12 m/s (t₁ = 4 s, t₂ = 15 s) · Distance = Area = ½vt₁ + vt₂ 9. On a speed-time graph, a train accelerates uniformly from rest to 22 m/s in 7 s and then continues at a constant speed of 22 m/s for a further 4 s. Calculate the total distance travelled.
v_max = 22 m/s (t₁ = 7 s, t₂ = 4 s) · Distance = Area = ½vt₁ + vt₂ 10. On a speed-time graph, a train accelerates uniformly from rest to 48 m/s in 6 s and then continues at a constant speed of 48 m/s for a further 7 s. Calculate the total distance travelled.
v_max = 48 m/s (t₁ = 6 s, t₂ = 7 s) · Distance = Area = ½vt₁ + vt₂ 11. On a speed-time graph, a train accelerates uniformly from rest to 26 m/s in 11 s and then continues at a constant speed of 26 m/s for a further 8 s. Calculate the total distance travelled.
v_max = 26 m/s (t₁ = 11 s, t₂ = 8 s) · Distance = Area = ½vt₁ + vt₂ 12. On a speed-time graph, a train accelerates uniformly from rest to 28 m/s in 10 s and then continues at a constant speed of 28 m/s for a further 10 s. Calculate the total distance travelled.
