If an object is dropped from a high cliff or a tall building, then the distance it has fallen after t seconds is given by the function h(t) = -16t^2. find the average rate of change in the first three seconds.

An object is accelerating at a constant rate. its velocity in feet per second as a function of time in seconds can be modeled by the linear function v(t) = 2.5t. what does the dependent variable represent for this function? a) acceleration b) distance c) slope d) velocity
