Kyle tosses a bone up in the air for his dog, Rover. The height, h, in feet, that Rover is above the ground at the time t seconds after he jumps for the bone
can be represented by the function, h(t) = -812 + 16+
What is Rover's average rate of ascent, in teet per second, from the time she
jumps into the air to the time she catches the bone at t = 72 second?
