Using Newton's Second Law (F = ma), if a constant net force of 60 N is applied to two different carts, Cart A (mass = 10 kg) and Cart B (mass = 20 kg), how will their accelerations compare?

Cart A will accelerate at 6 m/s2, which is twice the acceleration of Cart B (3 m/s2) Cart B will accelerate at 12 m/s2, which is twice the acceleration of Cart A Both carts will accelerate at the same rate of 60 m/s2 Cart A will remain stationary while Cart B accelerates

Correct Answer:

Cart A will accelerate at 6 m/s2, which is twice the acceleration of Cart B (3 m/s2)
