In drag racing, acceleration is more important than speed, and therefore drag racers are designed to provide high accelerations.  Suppose a drag racer has a mass of 1250 kg and accelerates at a rate of 16.5 m/s².  How large is the unbalanced force acting on the race car?

• 120,625 N
• 20,625 N
• 20,625 kg
• 120,625 N
