Work = Change in Kinetic energy
= 0.5 m (v² - u²)
= 0.5 × 2000 kg × [(19 × 5/18 m/s)² - (18 × 5/18 m/s)²]
≈ 2855 Joule
≈ 2.85 kJ
∴ Work done is approximately 2.85 kJ
= 0.5 m (v² - u²)
= 0.5 × 2000 kg × [(19 × 5/18 m/s)² - (18 × 5/18 m/s)²]
≈ 2855 Joule
≈ 2.85 kJ
∴ Work done is approximately 2.85 kJ
