Multiple Choice

Write an equation that expresses the relationship. Use k as the constant of variation.
-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 15 kilograms accelerates at a rate of 2 meters per second per second by a force, find the rate of acceleration of an object with a mass of 3 kilograms that is pulled by the same force.

A) 10 meters per second per second
B) $\frac { 2 } { 5 }$ meters per second per second
C) 8 meters per second per second
D) 5 meters per second per second
