Answer:

Power = 120000 watts

Step-by-step explanation:

mass = 2000kg

acceleration = 3m/s²

velocity = 20m/s

Force = mass x acceleration

Force = 2000 x 3 = 6000 Newton

Power = Force x velocity

Power = 6000 x 20 = 120000 watts

Since 1000 watts = 1kilo-watts

Power = 120000 watts or 120 kilo-watts
