GIVEN:

m = 28,456 lbs

m = 28,456 lbs × ( 1kg / 2.21 lbs )

m = 12, 876.02 kg

a = 9.8000 km/s²

a = 9.8000 km/s² × ( 1000m / 1km )

a = 9,800 m/s²

Net force = ?

SOLUTION:

F = ma

F = (12,876.02 kg) × (9,800 m/s²)

F = 126, 184, 996 N

ANSWER:

The net force needed for the truck to accelerate is 126, 184, 996 Newton or 126,185 kilo-Newton.
