Water Park Fun

This summer, my family took a trip to the water park. This picture is another example of velocity, acceleration and position. My brother is lying on a foam mat that slides downhill on the Volcano Express ride. Because it is a steep downhill ride, his velocity is constantly increasing because his speed is constantly increasing. His acceleration is also increasing. However, once he reaches the end of the ride and the slide levels out, his acceleration and velocity will begin to decrease. By the end of the ride, his mat will come to a complete stop and his final velocity will be zero just as his initial velocity was zero when he was at the top of the slide. Therefore, his average acceleration, which is his final velocity minus his initial velocity over the elapased time will be zero.
