Final answer:
Car A, with a mass of 750 kg, requires a force of 1500 N to accelerate at 2 m/s². Car B, having a mass of 1000 kg, needs a force of 2000 N for the same acceleration.
Step-by-step explanation:
The forces required to accelerate each car, given they accelerate at 2 m/s2, can be determined using Newton's second law of motion, F=ma, where F is the force, m is the mass, and a is the acceleration. For Car A with a mass of 750 kg, the force required is F = 750 kg × 2 m/s2 = 1500 N. Similarly, for Car B with a mass of 1000 kg, the force needed is F = 1000 kg × 2 m/s2 = 2000 N.
