SUV weight = 2,000 KG Rolling Resistance 15 kg/ton = 30 KG Wheel Radius = 0.3 m

System Efficiency Theory How much energy or force is needed at a speed of 50 km/hour?. SUV weight = 2,000 KG Rolling Resistance 15 kg/ton = 30 KG Wheel Radius = 0.3 m Necessary torque - 30 x 0.3 x 9.8 = 88 Nm Distance @ 50 km/h - 50,000/60 = 833 m/min
