Answer:
The acceleration of the mass is 2 meters per square second.
Explanation:
By Newton's second law, we know that force (), measured in newtons, is the product of mass (
), measured in kilograms, and net acceleration (
), measured in meters per square second. That is:
(1)
The initial force applied in the mass is:
In addition, we know that force is directly proportional to acceleration. If the smaller force is removed, then the initial force is reduced to of the initial force. The acceleration of the mass is:
The acceleration of the mass is 2 meters per square second.
