For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 28 N acts on
a certain
object, the acceleration of the object is 7 m/s². If the acceleration of the object becomes 3 m/s2, what is the force?

Answer:
Option C. The robin flies fastest because its rate is 15 m/s
Step-by-step explanation:
Let
x -----> the time in seconds
y ----> the distance in meters
The speed is equal to divide the distance by the time
In this problem, the slope or unit rate of the linear equation is the same that the speed
<em>Robin's Flight</em>
<em>Find the slope</em>
The formula to calculate the slope between two points is equal to
take two points from the table
(2,30) and (3,45)
substitute in the formula
<em>Cardinal's Flight</em>
<em>Blue Jay's Flight</em>
take two points from the graph
(0,0) and (2,20)
substitute in the formula
