As a 3.0-kg bucket is being lowered into a 10-m-deep well,starting from the top,the tension in the rope is 9.8 N.The acceleration of the bucket will be: A)6.5 m/s² downward. B)9.8 m/s² downward. C)zero. D)3.3 m/s²upward.

The net force on the bucket is the difference between gravitational force (mg = 3.0 kg * 9.8 m/s² = 29.4 N) and tension (9.8 N). The net force is 29.4 N - 9.8 N = 19.6 N downward. Using F = ma, the acceleration is 19.6 N / 3.0 kg = 6.5 m/s² downward.
