An object is dropped off a cliff and falls freely. it speeds up as it falls toward the ground. the graph below shows the velocity in meters per second (m/s) of the object (denoted by the vertical axis) as a function of time in seconds (denoted by the horizontal axis). note that the relationship is linear. this relationship is given by the equation, v = gt. in this equation, g is the acceleration due to gravity, t is the number of seconds, and v is the velocity of the falling object. note that g is a constant. find and interpret the meaning of the initial value and the rate of change in this context. the initial value is 9.8. that means that object’s initial velocity 9.8 m/s. the rate of change is 9.8. that means the acceleration due to gravity is 9.8 m/s2. the initial value is 0. that means that object’s initial velocity 0 m/s. the rate of change is 98. that means the acceleration due to gravity is 98.0 m/s2. the initial value is 0. that means that object’s initial velocity 0 m/s. the rate of change is 9.8. that means the acceleration due to gravity is 9.8 m/s2. the initial value is 9.8. that means that object’s initial velocity 9.8 m/s. the rate of change is 0.98. that means the acceleration due to gravity is 0.98 m/s2.
