Solve the problem.
-If the force acting on an object stays the same, then the acceleration of the object is inversely proportional to its mass. If an object with a mass of 21 kilograms accelerates at a rate of 9 meters per second per second by a force,
Find the rate of acceleration of an object with a mass of 7 kilograms that is pulled by the same force.
A) 18 meters per second per second
B) 24 meters per second per second
C) 3 meters per second per second
D) 27 meters per second per second

Quizplus · Accepted Answer

The acceleration of an object is inversely proportional to its mass when the force is constant. Therefore, if the mass is reduced to a third (from 21 kg to 7 kg), the acceleration will triple (from 9 m/s^2 to 27 m/s^2).
