24.)  The height s of a ball (in feet) at time t(in seconds) is given by the formula s(t)=64−16(t−1) s(t)=64−16(t−1)^2 . Consider the following expression.

AV[0.5,1]=s(1)−s(0.5)/1−0.5

Compute the value of AV[0.5,1]=

The curvature of the graph of ss on the interval 0.5≤t≤1. area. The area under the graph of ss on the interval 0.5≤t≤1. distance. The distance between the points (0.5,s(0.5)) and (1,s(1))(1,s(1)).

What does this value measure physically? average velocity. The average velocity of the ball during the interval 0.5≤t≤10.5≤t≤1. distance. The distance that the ball travels during the interval 0.5≤t≤10.5≤t≤1. direction. The direction that the ball traveling during the interval 0.5≤t≤10.5≤t≤1. acceleration.
