Answer = 30,000 N
EXPLANATION
Applying Newton’s second of law of motion, which in summary, states that the acceleration of an object... is directly proportional to the magnitude of the net force... and inversely proportional to the mass of the object.
Therefore, Force = Mass * Acceleration
F = ma
Mass, m = 3,000 kg
Acceleration, a = 10 m/s²
Force, F = 3,000 × 10
= 30,000 N
