Answer-

Work = Change in kinetic energy

Work = Change in kinetic energy = 0.5 m (v² - u²)

Work = Change in kinetic energy = 0.5 m (v² - u²)= 0.5 × 1500 kg × [(60 × 5/18 m/s)² - (30 × 5/18 m/s)²]

Work = Change in kinetic energy = 0.5 m (v² - u²)= 0.5 × 1500 kg × [(60 × 5/18 m/s)² - (30 × 5/18 m/s)²]= 156250 joules

Work = Change in kinetic energy = 0.5 m (v² - u²)= 0.5 × 1500 kg × [(60 × 5/18 m/s)² - (30 × 5/18 m/s)²]= 156250 joules= 156.25 kJ
