A person standing on the roof of a building throws a balldirectly upward. The ball misses the rooftop on its way downand eventually strikes the ground. The functions(1) = -16r + 64t + 80describes the ball's height above the ground, s(t), in feet,t seconds after it was thrown.a. Find the ball's average velocity between the time it wasthrown and 2 seconds later.b. Find the ball's average velocity between 2 and 4 secondsafter it was thrown.c. What do the signs in your answers to parts (a) and (b)mean in terms of the direction of the ball's motion?

Given data: The expression for the ball's height above the ground, st=-16t2+64t+80. Let t=0 s bet…
