-If the Force Acting on an Object Stays the Same

Solve.
-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 8 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) 24 meters per second per second
B) $\frac { 8 } { 3 }$ meters per second per second
C) 21 meters per second per second
D) 16 meters per second per second
