To calculate the distance covered in 36s, we need to first convert the speed from km/h to m/s:
Speed = 72 km/h = 72,000 m/3600 s = 20 m/s
Next, we can use the formula for distance covered:
distance = speed x time
distance = 20 m/s x 36 s
distance = 720 meters
Therefore, the distance covered in 36s is 720 meters.
To calculate the power required for that speed, we can use the formula:
Power = Traction resistance x speed
Power = 280 N/t x 201 t x 20 m/s
Power = 1120 kN m/s = 1120 kW
Therefore, the power required for that speed is 1120 kW.
A lorry with a mass of 201 has a traction resistance of 280N/t at a speed of 72km/h. Calculate
