Parts and their functions

• Velocity-time graph (वेग-समय ग्राफ़) — Slope = acceleration; then F = ma (m = 1500 kg).
• 0–5 s: speeding up (0–5 s: चाल बढ़ना) — a = (10 − 0)/5 = 2 m/s²; F = 1500 × 2 = 3000 N towards the east.
• 5–10 s: constant velocity (5–10 s: स्थिर वेग) — Flat line, a = 0, so the net force is zero (first law).
• 10–15 s: slowing down (10–15 s: चाल घटना) — a = (0 − 10)/5 = −2 m/s²; F = −3000 N, i.e. 3000 N towards the west (opposite to motion).
