210 whats ?
N/t is what? Newtons per ton or something?
anyway
power in watts = force in Newtons * velocity in meters per second
distance = speed * time,
remember 3600 seconds / hr and 1000 meters / km
A lorry with a mass of 210 has a tractive resistance of 280N/t at a speed of 72km/h .calculate the distance covered in 36s and the power required for that speed
